INNOVATION
The LoFLYTE® vehicle was the first
known powered flight of a hypersonic waverider configuration at low
speed, which proves that this shape can takeoff and land from a runway.
Accurate Automation has developed a neural controller representing the
first of a new generation of “smart” actuator controllers and a testbed
vehicle on which to test fly the neural control system.

ACCOMPLISHMENTS
- Designed and developed a hybrid/adaptive
controller which automatically adapts to changing flight environments,
such as speed, altitude, wind, and turbulence
- Designed a test apparatus to
allow evaluation of the performance of the hybrid neural/adaptive
controller in various flight environments and simulated the effect
of control surface and actuator damage
- Built a 100” wind tunnel model
and performed an extensive series of wind tunnel tests to evaluate
the low speed performance of a Mach 5 waverider configuration to
compare to real flight data
- Flight tested a 100” radio-controlled
model of a jet-powered vehicle with the 419th Flight Test Squadron
at the Air Force Flight Test Center at Edwards AFB
- Flight tested the neural network
flight control system
|
COMMERCIALIZATION
- The technologies developed in
this program were included in the proposal submitted by the Accurate
Automation-led team for NASA’s Future-X Pathfinder program.
- Accurate Automation has proposed
the use of this shape as a UCAV, a hypersonic cruise missile, and
a hypersonic target to the U.S. Navy.
- The LoFLYTE® team was awarded
a Small Business Administration Tibbetts Award in 1996.
- LoFLYTE®’s neural network
flight control system was awarded “Best of What’s New” by Popular
Science in 1996.
- Accurate Automation has licensed
this technology to a major aerospace corporation

GOVERNMENT/SCIENCE
APPLICATIONS
- The LoFLYTE® shape can be
scaled up to a faster and larger configuration for an unmanned combat
aerial vehicle, a cruise missile, or a hypersonic transport aircraft.
- The LoFLYTE® testbed aircraft
is being used to test additional aerospace technologies including
Accurate Automation’s Neural Air Data Sensor subsystem, neural network
engine controller, “Fly-by-Light” communi- cations protocol, an
advanced health monitoring system, and an advanced real-time data
acquisition and control system.
