Electric X-57: NASA’s Maxwell Electric X-57 is preparing for the Ground Vibration Test (GVT) at NASA’s Armstrong Flight Research Center in California.
The GVT was carried out in parallel to the controller tests of the cruise engine and tested the vehicle on various vibration levels.
It helped the engineers examine and validate the integrity of the vehicle for the flight conditions.
One of the goals of the X-57 is to help the Federal Aviation Administration set certification standards for emerging markets for electric aircraft.
NASA is expected to begin high-voltage ground operations tests for the organization’s first all-electric X-57 aircraft, the X-57 Maxwell, to help develop certification standards for emerging electric aircraft.
NASA is also helping these new electric aircraft by developing the quiet, efficient, and reliable technologies these vehicles require in normal use.
The tests will take place at NASA’s Armstrong Flight Research Center in Edwards, California.
This is an important milestone for the project as NASA moves from designing components and prototypes to operating in the vehicle as an airplane and taking a fundamental step towards the cabin. Tests and first flight.
Currently in its first configuration as an electric aircraft called the Mod 2, the X-57 will use a battery backup system for this phase of testing, which over time will draw power from a large high voltage power supply that will evolve the state of charge of Battery X. The control system is approaching.
The test should start at low power, review the start and stop sequences, and ensure that the new motor control software starts and controls the motors as intended.
This software and other key components were recently redesigned based on lessons learned from previous testing by the project’s prime contractor, Empirical Systems Aerospace or ESAero of San Luis Obispo, California.
These tests include driving the vehicle with more power. The X-57’s first pair of ESAero-supplied cruise electric motors are turned on and off so engineers can ensure that the vehicle’s propellers are spinning as intended.
It will monitor the acceleration of the engines to ensure they are delivering the expected performance by validating the vehicle’s instrumentation system and verifying that all of the sensors installed on the aircraft are functional.
This high voltage test will feed into the final verification and validation tests immediately, a critical final step before the shutdown tests begin.
“Most of the team doing this test will be the same one sitting in the flight control room, which is why I’m excited,” said Sean Clarke, NASA X-57 principal investigator.
“We designed the system, tested it in the laboratory, and handed it over to NASA’s flight and operating system engineers to actually use the vehicle.
