X-43A-LS in flight

Accurate Automation Corporation has been an active part of the hypersonic community for a number of years.  We provided the telemetry system for the NASA X-43A. Accurate Automation has conducted research in a number of hypersonic areas including:

• fault diagnosis  for fuel distribution subsystems
• unstart prediction
• non-destructive inspection
• neuro actuator control
• flush air data sensor
• scramjet flowpath design
• instrumentation
• adaptive engine control
• aircraft concept configurations
• flight control computers

As part of this aircraft development program, Accurate Automation has pursued the difficult testing of subsonic demonstrator vehicles. This includes a version of the NASA Hyper-X/X-43A vehicle, which is designated X-43A-LS. This remotely piloted vehicle (RPV) is a testbed for a series of research experiments including autolanding. Simultaneously, the X-43A-LS is providing subsonic flight data for the X-43 design. The X-43A-LS is powered by our AT-1500 turbojet.

The first flight was in fall of 2002 and the second flight was in the spring of 2003.
The most recent flights were in November 2003 when the X-43A-LS completed a series of flights at Eglin AFB, Florida.

Accurate Automation has proposed an X-43C configuration to NASA and is developing both subsonic and hypersonic vehicle configurations.
