A mechanic works on a General Electric I-40 turbojet at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. The military selected General Electric’s West Lynn facility in 1941 to secretly replicate the centrifugal turbojet engine designed by British engineer Frank Whittle. General Electric’s first attempt, the I-A, was fraught with problems. The design was improved somewhat with the subsequent I-16 engine. It was not until the engine's next reincarnation as the I-40 in 1943 that General Electric’s efforts paid off. The 4000-pound thrust I-40 was incorporated into the Lockheed Shooting Star airframe and successfully flown in June 1944. The Shooting Star became the US’s first successful jet aircraft and the first US aircraft to reach 500 miles per hour. The NACA’s Lewis Flight Propulsion Laboratory studied all of General Electric’s centrifugal turbojets both during World War II and afterwards. The entire Shooting Star aircraft was investigated in the Altitude Wind Tunnel during 1945. The researchers studied the engine compressor performance, thrust augmentation using a water injection, and compared different fuel blends in a single combustor. The mechanic in this photograph is inserting a combustion liner into one of the 14 combustor cans. The compressor, which is not yet installed in this photograph, pushed high pressure air into these combustors. There the air mixed with the fuel and was heated. The hot air was then forced through a rotating turbine that powered the engine before being expelled out the nozzle to produce thrust.

NASA’s all-electric X-57 Maxwell, in its Mod II configuration, departs Scaled Composites’ facility at Mojave Air and Space Port, en route to NASA’s Armstrong Flight Research Center in Edwards, California for delivery. The aircraft, shipped as two parts – the fuselage and the wing – was delivered to NASA Armstrong’s Research Aircraft Integration Facility, where it will be reintegrated to begin ground tests, to be followed by taxi tests, and eventually, flight tests. X-57’s Mod II configuration, the first of three primary modifications for the project, involves testing of the aircraft’s cruise electric propulsion system. The goal of the X-57 project is to share the aircraft’s electric-propulsion-focused design and airworthiness process with regulators, to advance certification approaches for distributed electric propulsion in general aviation.

Advanced eLectrical Bus (ALBus) CubeSat: From Build to Flight A new CubeSat, launched Sunday, December 16, will test high power electric systems and the use of unique shape memory alloy (SMA) components for the first time. CubeSats are very small, lightweight satellites, about the size of a loaf of bread, and typically operate within a power range of 5-20 watts. Lower power systems are typically used in CubeSats because of size and weight limits, while higher power systems and components cause excessive heat. Completely designed and led by a team of 12 early career scientists and engineers at NASA’s Glenn Research Center in Cleveland, the Advanced Electrical Bus, or ALBus, will be the first CubeSat to demonstrate power management and distribution of a 100-watt electrical system. The CubeSat will also employ a custom-built SMA release mechanism and hinges to deploy solar arrays and conduct electricity.

Delivery to NASA from prime contractor Empirical Systems Aerospace of San Luis Obispo, California, marks a major milestone for the project, at which point the vehicle is reintegrated for ground tests, to be followed by taxi tests, and eventually, flight tests. X-57's goal is to further advance the design and airworthiness process for distributed electric propulsion technology for general aviation aircraft, which can provide multiple benefits to efficiency, emissions, and noise.

Engineers monitor data during vibration testing of a cruise motor controller for the X-57 Maxwell, NASA's first all-electric X-plane. Attached to a table at NASA Armstrong Flight Research Center's environmental lab, the cruise motor controller is exposed to specific levels of vibration, allowing NASA to examine the structural integrity of the hardware. Engineers, meanwhile, monitored data, including waveforms of electrical current, and recorded readings.
