FRG's unique aircraft identification algorithm
not only estimates aerodynamic parameters
from flight test data to develop dynamic
models but also verifies the sensor consistency
and accuracy. Sensor errors such as biases
and scale factors are estimated as part
of the aircraft parameter identification
process.
FRG routinely uses the aircraft identification
algorithm to update the aerodynamic models
of its In-Flight Simulators. Model updates
are made both to linear and non-linear aerodynamic
parameters and to wind tunnel table look-up
data.
FRG provides complete model development
assistance to its customers. This includes:
Supplying and installing the aircraft
identification algorithm at the customer
facility
Identification algorithm training
Assistance in developing fight test
program for and unique maneuvers aerodynamic
model development
Flight data analysis assistance
PID software has been used extensively to update the VISTA aerodynamic model.
FRG has extensive experience in
Flight Control analysis, design and development.
It has designed and implemented the digital
Fly-By-Wire (FBW) flight control systems
for all its In-Flight Simulator aircraft.
FRG has provided assistance to
several aircraft development programs. Assistance
has included Flight Control System analysis,
ground simulation evaluations and In-Flight
Simulation implementation and evaluations.
Calspan's experienced test
pilots and control engineers bring a unique
perspective to the assistance we offer to
our customers having been exposed many designs.
Calspan has provided flight qualities
and flight control development expertise
to numerous aircraft development programs
in support of the prime manufacturers and
systems program offices. These programs
have included the B-1, B-2, YF-22, YF-23,
F-22, National AeroSpace Plane X-30, Space
Shuttle, Sweden's JAS-39 Gripen, and Israel's
Lavi, among others.
FRG has a long heritage in the
development of aircraft flying quality research
going back to our earliest years.
We have established the methods
and techniques for analysis of aircraft
flying qualities and pilot-in-the-loop evaluation
of control system designs, including the
development of the Cooper-Harper Pilot Rating
scale with NASA.
FRG helped collect much of the
data needed for handling qualities criteria
development and contributed to the
Military Specification for Flying
Qualities of Piloted Airplanes (MIL-F-8785B)
and
Military Specification for the
Flying Qualities of Piloted Vertical
or Short Takeoff Or Landing Aircraft
(MIL-F-83300).
FRG developed the Neal-Smith handling
qualities criterion which has been used
extensively in flight control analysis.
Calspan has provided handling
qualities evaluation assistance to many
aircraft development programs.
