AT-1500 Air Start Engine |
|
Accurate Automation Corporation has developed a high performance, low-cost turbojet engine for use in UAVs, air-launched missiles, targets, and decoys. The engine, designated the AT-1500 has been developed under the Navy's Small Business Innovative Research (SBIR) program.. This low cost engine is specifically designed for long storage life and zero-maintenance. The engine is 15" long, 8.6" maximum diameter, weighs 19-lbf (installed) and produces 150-lbf of thrust at sea level, static conditions.
The engine is currently being flown on the NASA X-43A-LS UAV(currently in flight test at Eglin AFB). Flight testing with the AT-1500 started in 2001 and is ongoing. More information about X-43A-LS or Accurate's FlightTest activities can be found by contacting Accurate Automation Corporation.
The AT-1500 engine is equipped with an automatic start system for air-launched applications. All start tests have resulted in a 100% success rate.
As part of the family of higher performance turbojets, the AT-1500 is being expanded for more thrust. The AT-1700 turbojet has the same dimensions and weight as the AT-1500 and has ~80% parts commonality with the AT-1500. It develops over 200-lbf of thrust (sea-level, static). The AT-1700 and AT-1500 use common air-start, control and fuel systems.
