XV-3 HOVERING ON RAMP. Flight Test of Bell XV-3 Convertiplane. Bell VTOL tilt-rotor aircraft hovering in front of building N-211 at Moffett Field. The XV-3 design combined a helicopter rotor and a wing. A 450 horsepower Pratt & Whitney piston engine drove the two rotors. The XV-3, first flown in 1955 , was the first tilt-rotor to achieve 100% tilting of rotors. The vehicle was underpowered, however, and could not hover out of ground effect. Note the large ventral fin, which was added to imrpove directional stability in cruse (Oct 1962)

The Rotorcycle was a small, 500pound, single-place helicopter. Tests indicated that the vehicle was unsafe because of low yaw-control capability to the right; the design also had oor crashworthiness.

NASA's Project Morpheus prototype lander is prepared for lifting by a crane in preparation for a tethered-flight test at the north end of the Shuttle Landing Facility at NASA’s Kennedy Space Center in Florida. For the 40-second test, the lander will be hoisted 20 feet. The spacecraft will ascend an additional five feet and hover for five seconds. Morpheus then will perform a 5.6-foot ascent coupled with a 9.8-foot traverse, and hover for five more seconds before returning to the launch point. A number of changes have been made, primarily focused on autonomous landing and hazard avoidance technology ALHAT and moving the Doppler Lidar to the front of the forward liquid oxygen tank. The tether test was cut short due to Morpheus exceeding onboard abort rate limits. The vehicle was taken back to the hangar and data from the test is being studied. After review, managers will determine when a new test date will be set. The landing facility provides the lander with the kind of field necessary for realistic testing, complete with rocks, craters and hazards to avoid. Morpheus’ ALHAT payload allows it to navigate to clear landing sites amidst rocks, craters and other hazards during its descent.

NASA's Ingenuity Mars Helicopter hovers and rotates over Jezero Crater during its second experimental flight test on April 22, 2021. The footage was captured by the Mastcam-Z imager, a pair of zoomable cameras aboard NASA's Perseverance Mars rover. Altimeter data from the solar-powered helicopter indicates it climbed to its prescribed maximum altitude of 16 feet (5 meters), flew downrange 7 feet (2 meters) and returned, performed several turns while in a hover, and landed. Total flight time 51.9 seconds. Flying in a controlled manner on Mars is far more difficult than flying on Earth. The Red Planet has significant gravity (about one-third that of Earth's), but an atmosphere with only about 1% of the density at Earth's surface. Stitched together from multiple images, the mosaic is not white balanced; instead, it is displayed in a preliminary calibrated version of a natural-color composite, approximately simulating the colors of the scene as it would appear on Mars. Arizona State University in Tempe leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego. The Ingenuity Mars Helicopter was built by JPL, which also manages this technology demonstration project for NASA Headquarters. It is supported by NASA's Science Mission Directorate, Aeronautics Research Mission Directorate, and Space Technology Mission Directorate. NASA's Ames Research Center and Langley Research Center provided significant flight performance analysis and technical assistance during Ingenuity's development. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

CAPE CANAVERAL, Fla. – At NASA’s Kennedy Space Center in Florida, the Project Morpheus prototype lander has been lifted by a tether and hovers above a transportable launch platform positioned at the north end of the Shuttle Landing Facility. The lander’s engine begins firing for a tethered test that includes lifting it 20 feet by crane, ascending another 10 feet, maneuvering backwards 10 feet, and then flying forward and descending to its original position, landing at the end of the tether. Testing of the prototype lander was performed at NASA’s Johnson Space Center in Houston in preparation for tethered and free flight testing at Kennedy. The landing facility will provide the lander with the kind of field necessary for realistic testing, complete with rocks, craters and hazards to avoid. Morpheus utilizes an autonomous landing and hazard avoidance technology, or ALHAT, payload that will allow it to navigate to clear landing sites amidst rocks, craters and other hazards during its descent. Project Morpheus is being managed under the Advanced Exploration Systems, or AES, Division in NASA’s Human Exploration and Operations Mission Directorate. The efforts in AES pioneer new approaches for rapidly developing prototype systems, demonstrating key capabilities and validating operational concepts for future human missions beyond Earth orbit.

KENNEDY SPACE CENTER, FLA. -- In Building 1555 on North Vandenberg Air Force Base in California, technicians work on the separation system to be mated to the AIM spacecraft, hovering above it. AIM, which stands for Aeronomy of Ice in the Mesosphere, is being prepared for integrated testing and a flight simulation. The AIM spacecraft will fly three instruments designed to study polar mesospheric clouds located at the edge of space, 50 miles above the Earth's surface in the coldest part of the planet's atmosphere. The mission's primary goal is to explain why these clouds form and what has caused them to become brighter and more numerous and appear at lower latitudes in recent years. AIM's results will provide the basis for the study of long-term variability in the mesospheric climate and its relationship to global climate change. AIM is scheduled to be mated to its launch vehicle, Orbital Sciences' Pegasus XL, during the second week of April, after which final inspections will be conducted. Launch is scheduled for April 25.

The move was scheduled for 12:30 a.m., but was postponed until 10 p.m. so technicians could resolve an issue with a leveling system on the crawler-transporter. Once inside the VAB, Discovery's external fuel tank will be examined and foam reapplied where 89 sensors were installed on the tank's aluminum skin for an instrumented tanking test on Dec. 17. The sensors were used to measure changes in the tank as super-cold propellants were pumped in and drained out. Data and analysis from the test will be used to determine what caused the tops of two, 21-foot-long support beams, called stringers, on the outside of the intertank to crack during fueling on Nov. 5. Discovery's next launch opportunity is no earlier than Feb. 3, 2011. For more information on STS-133, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts133/.

CAPE CANAVERAL, Fla. – An orbital maneuvering system, or OMS, pod hovers above its transporter in Orbiter Processing Facility-1 at NASA’s Kennedy Space Center in Florida. The pod will be reinstalled on space shuttle Atlantis. The orbital maneuvering system provided the shuttle with thrust for orbit insertion, rendezvous and deorbit, and could provide up to 1,000 pounds of propellant to the aft reaction control system. The OMS is housed in two independent pods located on each side of the shuttle's aft fuselage. Each pod contains one OMS engine and the hardware needed to pressurize, store and distribute the propellants to perform the velocity maneuvers. Atlantis’ OMS pods were removed and sent to White Sands Test Facility in New Mexico to be cleaned of residual toxic propellant. The work is part of the Space Shuttle Program’s transition and retirement processing of the shuttle fleet. A groundbreaking was held Jan. 18 for Atlantis' future home, a 65,000-square-foot exhibit hall in Shuttle Plaza at the Kennedy Space Center Visitor Complex. Atlantis is scheduled to roll over to the visitor complex in November in preparation for the exhibit’s grand opening in July 2013. For more information, visit http://www.nasa.gov/transition.

VANDENBERG AIR FORCE BASE, Calif. -- In the airlock of processing facility 1555 at Vandenberg Air Force Base (VAFB) in California, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) hovers above its shipping container during transfer to a handling dolly. The spacecraft arrived at VAFB Jan. 27 after a cross-country trip which began from Orbital Sciences' manufacturing plant in Dulles, Va., on Jan. 24. Next, NuSTAR will be transferred from the airlock into the processing hangar, joining the Pegasus XL rocket that is set to carry it to space. After checkout and other processing activities are complete, the spacecraft will be integrated with the Pegasus in mid-February and encapsulation in the vehicle fairing will follow. The rocket and spacecraft then will be flown on Orbital's L-1011 carrier aircraft to the Ronald Reagan Ballistic Missile Defense Test Site at the Pacific Ocean's Kwajalein Atoll for launch in March. The high-energy X-ray telescope will conduct a census for black holes, map radioactive material in young supernovae remnants, and study the origins of cosmic rays and the extreme physics around collapsed stars.

KENNEDY SPACE CENTER, FLA. -- In Building 1555 on North Vandenberg Air Force Base in California, technicians carry the separation system, at left, toward the AIM spacecraft hovering above the stand at right. AIM, which stands for Aeronomy of Ice in the Mesosphere, is being prepared for integrated testing and a flight simulation. The AIM spacecraft will fly three instruments designed to study polar mesospheric clouds located at the edge of space, 50 miles above the Earth's surface in the coldest part of the planet's atmosphere. The mission's primary goal is to explain why these clouds form and what has caused them to become brighter and more numerous and appear at lower latitudes in recent years. AIM's results will provide the basis for the study of long-term variability in the mesospheric climate and its relationship to global climate change. AIM is scheduled to be mated to its launch vehicle, Orbital Sciences' Pegasus XL, during the second week of April, after which final inspections will be conducted. Launch is scheduled for April 25.

CAPE CANAVERAL, Fla. – The first free flight of the Project Morpheus prototype lander was conducted at the Shuttle Landing Facility at NASA’s Kennedy Space Center in Florida. Smoke filled the air as the engine fired and the Morpheus lander launched from the ground over a flame trench. During the 54-second test, it ascended approximately 50 feet, and hovered for about 15 seconds. The lander then flew forward and landed on its pad about 23 feet from the launch point. Testing of the prototype lander was performed at NASA’s Johnson Space Center in Houston in preparation for tethered and free flight testing at Kennedy. Project Morpheus integrates NASA’s automated landing and hazard avoidance technology, or ALHAT, with an engine that runs on liquid oxygen and methane, or green propellants, into a fully-operational lander that could deliver cargo to asteroids and other planetary surfaces. The landing facility will provide the lander with the kind of field necessary for realistic testing, complete with rocks, craters and hazards to avoid. Morpheus’ ALHAT payload allows it to navigate to clear landing sites amidst rocks, craters and other hazards during its descent. Project Morpheus is being managed under the Advanced Exploration Systems, or AES, Division in NASA’s Human Exploration and Operations Mission Directorate. The efforts in AES pioneer new approaches for rapidly developing prototype systems, demonstrating key capabilities and validating operational concepts for future human missions beyond Earth orbit.

LLRV flight #1-16-61F with Bell 47 Helicopter providing chase support. The use of chase planes was a critical part of flight research well before the establishment of what was then called the NACA Muroc Flight Test Unit in September 1947 (now the NASA Dryden Flight Research Center). They act as a second set of eyes for the research pilot, warning him of any problems. When test flights of the LLRV began in October 1964, chase support for the vehicle was supplied by a Bell 47 helicopter. It could hover close by, providing information such as altitude and descent rate. LLRV test operations were phased out in late 1966 and early 1967. When Apollo planning was underway in 1960, NASA was looking for a simulator to profile the descent to the Moon's surface. Three concepts surfaced: an electronic simulator, a tethered device, and the ambitious Dryden contribution, a free-flying vehicle. All three became serious projects, but eventually the NASA Flight Research Center’s (FRC) Lunar Landing Research Vehicle (LLRV) became the most significant one. After conceptual planning and meetings with engineers from Bell Aerosystems Company, Buffalo, N.Y., NASA FRC issued a $3.6 million production contract awarded in 1963, for delivery of the first of two vehicles for flight studies. Built of tubular aluminum alloy like a giant four-legged bedstead, the vehicle was to simulate a lunar landing profile from around 1500 feet to the Moon’s surface. The LLRV had a turbofan engine mounted vertically in a gimbal, with 4200 pounds of thrust. The engine, lifted the vehicle up to the test altitude and was then throttled back to support five-sixths of the vehicle's weight, thus simulating the reduced gravity of the Moon. Two lift rockets with thrust that could be varied from 100 to 500 pounds handled the LLRV's rate of descent and horizontal translations. Sixteen smaller rockets, mounted in pairs, gave the pilot control in pitch, yaw, and roll. The pilot’s platform extended forward between t

NASA's Perseverance Mars rover captured this video of the Ingenuity Mars Helicopter's 54th flight on Aug. 3, 2023. After performing a preflight "wiggle check" with its rotors, the helicopter takes off, hovers at an altitude of 16 feet (5 meters), and rotates to the left, before touching back down. The mission conducted the short pop-up flight to check Ingenuity's navigation system. The video was captured by the rover's Mastcam-Z imager from a distance of about 180 feet (55 meters). Arizona State University in Tempe leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Niels Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

The XV-15 tilt rotor ships #1 and #2 parked on the NASA Dryden Flight Research Center ramp. The XV-15s, manufactured by Bell, were involved in limited research at Dryden in 1980 and 1981. The development of the XV-15 Tiltrotor research aircraft was initiated in 1973 with joint Army/NASA funding as a "proof of concept", or "technology demonstrator" program, with two aircraft being built by Bell Helicopter Textron (BHT) in 1977. The aircraft are powered by twin Lycoming T-53 turboshaft engines that are connected by a cross-shaft and drive three-bladed, 25 ft diameter metal rotors (the size extensively tested in a wind tunnel). The engines and main transmissions are located in wingtip nacelles to minimize the operational loads on the cross-shaft system and, with the rotors, tilt as a single unit. For takeoff, the proprotors and their engines are used in the straight-up position where the thrust is directed downward. The XV-15 then climbs vertically into the air like a helicopter. In this VTOL mode, the vehicle can lift off and hover for approximately one hour. Once off the ground, the XV-15 has the ability to fly in one of two different modes. It can fly as a helicopter, in the partially converted airplane mode. The XV-15 can also then convert from the helicopter mode to the airplane mode. This is accomplished by continuous rotation of the proprotors from the helicopter rotor position to the conventional airplane propeller position. During the ten to fifteen second conversion period, the aircraft speed increases and lift is transferred from the rotors to the wing. To land, the proprotors are rotated up to the helicopter rotor position and flown as a helicopter to a vertical landing.

On Aug. 17 and 18, 2023, engineers at NASA's Jet Propulsion Laboratory in Southern California tested the landing system for a proposed future mission that would touch down on Jupiter's icy moon Europa. This system for the proposed Europa Lander is an evolution of hardware used on previous NASA lander missions. It includes the architecture used for the "sky crane maneuver" that helped lower NASA's Curiosity and Perseverance rovers onto the Martian surface, which would give the lander the stability it needs during touchdown. Although this landing architecture was developed with Europa as the target, it could be adapted for use at other moons and celestial bodies with challenging terrain. Four bridles, suspended from an overhead simulated propulsive descent stage, maintain a level lander body. The four legs conform passively to the terrain they encounter as the lander body continues to descend toward the surface. Each leg consists of a four-bar linkage mechanism that controls the leg's pose before and during landing. The legs are preloaded downward with a constant force spring to help them rearrange and compress the surface they encounter prior to landing, giving them extra traction and stability during and after the landing event. Acting like a skid plate, the belly pan provides the underside of the spacecraft with protection from potentially harmful terrain. The belly pan also resists shear motion on the terrain it interacts with. Once the belly pan contacts the surface, sensors trigger a mechanism that quickly locks the legs' "hip" and "knee" rotary joints, resulting in a table-like stance. At this point, the job of ensuring lander stability shifts from the bridles to the legs. This shift keeps the lander level after the bridles are unloaded. In the event the belly pan does not encounter terrain during the touchdown process, sensors in each leg can also declare touchdown. After the leg joints lock, the belly pan would be suspended above the landed terrain, and the lander would be supported only by the four legs. Not pictured in the video is the period after the bridles are offloaded and flyaway is commanded. The bridles would then be cut, and the hovering propulsive stage would fly away, leaving the lander in a stable stance on the surface.
