Armstrong Celebrates 75 Years

NASA Armstrong began celebrating its 75th anniversary Sept. 30, the day that 13 National Advisory Committee for Aeronautics employees established a unit here in 1946 to support the X-1 and the quest to break the sound barrier.

As part of the celebration, a time capsule prepared in 1996 was opened Oct. 13 and the capsule items were unloaded. NASA Administrator Bill Nelson, NASA Deputy Administrator Pam Melroy, NASA Armstrong Center Director David McBride, and Deputy Director Pat Stoliker reviewed the treasures. Andy Blua and Don Whitfield, who helped build the time capsule and still work at the center, were invited to watch as the artifacts they helped safely store were unpacked.

X-59

The X-59 Quiet SuperSonic Technology accomplished major milestones in 2021 that gained national attention and positioned the Low-Boom Flight Demonstration mission for a promising 2022. As the X-59 took shape in 2021, teams at NASA Armstrong prepared the X-plane’s future hangar, while hardware and techniques for the X-plane’s future acoustic validation research were advanced inflight. A contract was also awarded to handle the cutting-edge ground recording system that will measure the unique quiet thumps heard on the ground as the X-59 passes at supersonic speeds overhead. The aircraft, overcoming great challenges related to the pandemic, completed its initial assembly, and was shipped to Fort Worth, Texas for its first ground tests. 

NASA’s all-electric X-57 Maxwell completed high-voltage ground testing with successful spinning of the propellers under electric power at NASA’s Armstrong Flight Research Center in California. The principal goals of the X-57 project are to share the X-57 design and airworthiness process with regulators and standards organizations; and to establish the X-57 as a reference platform for integrated approaches of distributed electric propulsion technologies.

X-57

High-voltage ground testing took place on NASA’s first all-electric X-plane, the X-57 Maxwell. The X-57, which is in its first configuration called Mod II, drew power from a large, off-aircraft high-voltage power supply for these tests at NASA Armstrong. A highlight from high-voltage testing included the spinning of the propellers for the first time under electric power. Though the propellers had previously spun during the X-57’s initial build phase conducted by the small business prime contractor Empirical Systems Aerospace, Inc. at Scaled Composites in Mojave, it is now up to NASA engineers to advance the system and use lessons learned from previous tests. The X-57 team continues to prepare the aircraft for the first flight in the Mod II configuration in the spring.

Advanced Air Mobility National Campaign

NASA’s Advanced Air Mobility National Campaign crossed through several barriers this year in the pursuit of integrating electric vertical takeoff and landing or eVTOL aircraft into the National Airspace System or NAS. The team opened solicitations for new industry partners to join the National Campaign and completed signingsJoby’s eVTOL was flown in several flight scenarios including flights to test the noise of the aircraft. The team also flew an OH-58 helicopter like a surrogate urban air mobility vehicle to prepare for the Joby flight and others. Projects and sub-projects under the Advanced Air Mobility Mission are all working towards the common goal of researching what it will take to integrate these vehicles into the NAS.

The uncrewed HiDRON stratospheric glider from Stratodynamics is designed to release from a sounding balloon at near-space altitude, enabling a controlled descent for technology payloads aboard. The glider also achieves higher velocity than a balloon flight alone – one of the reasons NASA-supported researchers from the University of Kentucky chose Stratodynamics as the flight provider for testing of turbulence detection instruments.

Flight Opportunities

Video capture during future lunar landings could play an important role in contributing to researchers’ understanding of disturbances in lunar surface materials – called regolith – caused by the lander’s rocket plume. The desert environment of Mojave, California, provided a stand-in for the surface of the Moon, and the Xodiac vertical takeoff vertical landing (VTVL) platform from Masten Space Systems was the test vehicle. Another highlight for Flight Opportunities took place between June 1 and 6 when Stratodynamics Inc. of Lewes, Delaware, launched its HiDRON stratospheric glider from a high-altitude balloon at Spaceport America in New Mexico carrying technology supported by NASA’s Flight Opportunities program for the first time.

Stratospheric Observatory for Infrared Astronomy (SOFIA)

In July, NASA’s Stratospheric Observatory for Infrared Astronomy deployed to Tahiti, French Polynesia to study celestial objects best observed from the Southern Hemisphere. The team completed 13 successful flights before returning early due to updated COVID-19 precautions. For the first time since 2008, SOFIA’s upper rigid door was removed during its annual maintenance period. The upper rigid door is one of the key aspects of SOFIA that allows the observatory to operate. As the largest airborne observatory in the world, SOFIA allows scientists to study observations that are not visible from telescopes on the ground.

This software has the potential to save aircraft ranging from general aviation to future autonomous aircraft. The pilot in this case is flying a Cessna 172SP aircraft in the Sierra Nevada mountains evaluating the iGCAS for use under bush pilot conditions. The iGCAS display is shown on the right activating because of severe downdraft winds. (Credits: NASA/Mark Skoog)

Resilient Autonomy

Resilient Autonomy ended in September, but accomplished several goals in 2021. The team worked with the Federal Aviation Administration (FAA) and the U.S. Department of Defense (DoD), to create new autonomous aircraft technology called EVAA or Expandable Variable Autonomy Architecture. EVAA could help prevent accidents in retrofit general aviation aircraft and future autonomous aircraft. The DoD, the FAA and other groups such as the Alaska bush pilot community are looking into how this software could be integrated into a variety of aircraft. The EVAA software is now managed under the NASA Armstrong Center Technology Transfer office.

NASA STEM

Most of NASA Armstrong’s Office of STEM Engagement activities took place in a virtual environment in 2021, but the activities still made large impacts. Through the Minority University Research and Education Project’s Institutional Research Opportunity (MIRO), students attending Minority Serving Institutions (MSIs) studied the potential space applications of carbon nanotubes. Three interns funded through Space Grant worked on Armstrong projects such as Preliminary Research Aerodynamic Design to Land on Mars (Prandtl-M) and the Revolutionary Vertical Lift Technology (RVLT) project. One Armstrong intern team even worked on the Greater Heights Project – a virtual reality experience allowing people to “fly” the X-15 rocket plane. Armstrong’s Office of STEM Engagement continually collaborates with the regional STEM community to support education programs that are designed to foster the growth of a diverse STEM workforce.
