This image depicts the Saturn I launch vehicle placed in the dynamic test stand at the Marshall Space Flight Center (MSFC). A dummy booster was moved to the dynamic test stand early in June, and, for the first time, vertically mated with dummy S-I and S-IV stages. The assembled vehicle was readied for dynamic testing to investigate the integrity of the support structure.

An aircraft body modeled after an air taxi with weighted test dummies inside is being prepared for a drop test by researchers at NASA’s Langley Research Center in Hampton, Virginia. The test was completed June 26 at Langley’s Landing and Impact Research Facility. The aircraft was dropped from a tall steel structure, known as a gantry, after being hoisted about 35 feet in the air by cables. NASA researchers are investigating aircraft materials that best absorb impact forces in a crash.

Engineers working with Boeing's CST-100 Starliner test the spacecraft's seat design in Mesa, Arizona, focusing on how the spacecraft seats would protect an astronaut's head, neck and spine during the 240-mile descent from the International Space Station. The company incorporated test dummies for a detailed analysis of impacts on a crew returning to earth. The human-sized dummies were equipped with sensitive instrumentation and secured in the seats for 30 drop tests at varying heights, angles, velocities and seat orientations in order to mimic actual landing conditions. High-speed cameras captured the footage for further analysis. The Starliner spacecraft is being developed in partnership with NASA's Commercial Crew Program.

NASA Drop Test Supports Safer Air Taxi Designs
On April 6, 2016, engineers at NASA’s Langley Research Center in Hampton, Virginia, kicked off a series of nine drop tests of a representative Orion crew capsule with crash test dummies inside to understand what the spacecraft and astronauts may experience when landing in the Pacific Ocean after deep-space missions. The high-fidelity capsule, coupled with the heat shield from Orion's first flight in space, was hoisted approximately 16 feet above the water and vertically dropped into Langley’s 20-foot-deep Hydro Impact Basin. The crash test dummies were instrumented to provide data and secured inside the capsule to help provide information engineers need to ensure astronauts will be protected from injury during splashdown. Each test in the series simulates different scenarios for Orion’s parachute-assisted landings, wind conditions, velocities and wave heights the spacecraft may experience when touching down in the ocean.

The M2-F1 was fitted with an ejection seat before the airtow flights began. The project selected the seat used in the T-37 as modified by the Weber Company to use a rocket rather than a ballistic charge for ejection. To test the ejection seat, the Flight Research Center's Dick Klein constructed a plywood mockup of the M2-F1's top deck and canopy. On the first firings, the test was unsuccessful, but on the final test the dummy in the seat landed safely. The M2-F1 ejection seat was later used in the two Lunar Landing Research Vehicles and the three Lunar Landing Training Vehicles. Three of them crashed, but in each case the pilot ejected from the vehicle successfully.

U.S. Navy recovery team members practice bringing an astronaut aboard the USS John P. Murtha, using a dummy, during Underway Recovery Test-7 (URT-7) on Nov. 5, 2018. NASA's Recovery Team, along with the U.S. Navy, are practicing recovery of a test version of the Orion in the Pacific Ocean. URT-7 is one in a series of tests to verify and validate procedures and hardware that will be used to recover the Orion spacecraft after it splashes down in the Pacific Ocean following deep space exploration missions. Orion will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities.

Engineers and technicians at the Marshall Space Flight Center placed a Saturn V ground test booster (S-IC-D) into the dynamic test stand. The stand was constructed to test the integrity of the vehicle. Forces were applied to the tail of the vehicle to simulate the engines thrusting, and various other flight factors were fed to the vehicle to test reactions. The Saturn V launch vehicle, with the Apollo spacecraft, was subjected to more than 450 hours of shaking. The photograph shows the 300,000 pound S-IC stage being lifted from its transporter into place inside the 360-foot tall test stand. This dynamic test booster has one dummy F-1 engine and weight simulators are used at the other four engine positions.

Sailors from the USS Anchorage simulate “Oscar,” a dummy used for man overboard drills, to the medical unit. During Underway Recovery Test 6, the USS Anchorage’s man overboard drill gave Kennedy Space Center’s NASA Recovery Team a glimpse of one way an astronaut could be brought from a small boat onto the ship using a stretcher. Once the Orion capsule splashes down in the Pacific Ocean, astronauts can choose to stay in the capsule until it is pulled into the well deck of the Navy vessel, or have a diver retrieve them in the open water and then get the capsule later.

Howard Hasbrook volunteers for a demonstration of a scaled-down version of Lieutenant Colonel John Stapp’s rocket sled set up in the hangar at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. In 1945 Stapp, an Air Force medical doctor, volunteered to participate in a deceleration program to study the human body’s tolerance to aircraft crash forces. A 1500-pound sled powered by rockets was installed in 1947 on a section of railroad track in the California desert. Stapp participated in 29 experiments over the next seven years and broke land and deceleration records. These tests studied the effects of acceleration, G-force, deceleration, and wind blast on humans. Stapp suffered broken bones and retinal hemorrhages, but suffered no permanent damage.     NACA Lewis was conducting a series of crash impact studies in the mid-1950s using dummies in actual aircraft. Irving Pinkel, the director of the program, and Stapp became friends through their mutual interest in this field. In April 1956 Stapp visited the Cleveland lab to give a talk to the local section of the American Rocket Society that discussed issues relating to the escape of pilots from the cockpit of supersonic jet aircraft. That same week, NACA Lewis’ Pinkel, Gerard Pesman, Merritt Preston, and Dugald Black received the annual Laura Taber Barbour Air Safety Award for their work on the Crash Fire Program. Black and Preston are visible in the crowd in this photograph.

A researcher at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory prepares for a test of an NACA-designed aircraft seat. The laboratory had undertaken a multi-year investigation into the causes and prevention of fires on low altitude aircraft crashes. The program was expanded in the mid-1950s to include the study of impact on passengers, types of seat restraints, and seat design.      The crash impact portion of the program began by purposely wrecking surplus Fairchild C-82 Packet and Piper Cub aircraft into barricades at the end of a test runway at the Ravenna Arsenal, located approximately 40 miles south of the Lewis lab in Cleveland. Instrumented dummies and cameras were installed in the pilot and passenger areas. After determining the different loads and their effects on the passengers, the NACA researchers began designing new types of seats and restraints.     The result was an elastic seat that flexed upon impact, absorbing 75 percent of the loads before it slowly recoiled. This photograph shows the seats mounted on a pendulum with a large spring behind the platform to provide the jolt that mimicked the forces of a crash. The seat was constructed without any potentially damaging metal parts and included rubber-like material, an inflated back and arms, and a seat cushion. After the pendulum tests, the researchers compared the flexible seats to the rigid seats during a crash of a transport aircraft. They found the passengers in the rigid seats received 66 percent higher g-forces than the NACA-designed seats.
