Aircraft Simulation Environment Tool
Product The Aircraft Simulation Environment Tool
(ASET) is a Concept-to-Sim tool designed for
LaRC researchers. ASET is shown in the middle of
the page surrounded by various research functions
facilitated by the ASET design environment. By
providing a design testbed, in a real-time
simulation environment, ASET facilitates fight
dynamics analysis, flight control law
development, system identification, and modeling
research for advanced aerospace configurations.
An important feature of this tool is its specific
capability to allow researchers to work in
CAD/CAE environments (e.g. Matlab) or user codes
(ftn,c,c) and seamlessly carry their algorithms
(control laws, models, etc.) directly to LaRC
simulators, such as DMS shown in the lower
right-hand corner of the graphic. ASET provides a
full 6 d.o.f. nonlinear simulation capability,
GUI or script interfaces, linear model
computations at trim or on the fly, and numerous
other important capabilities and options that
assist researchers. An important feature is that
ASET allows researchers to easily and rapidly
change the vehicle and/or its subsystems such as
sensors, actuators, control laws, etc., without
having to rebuild the entire simulation. The
concept is analogous to a record player, where
ASET is the record player (that does not change)
and different vehicles or subsystems being
modeled are records that are readily changed in
the player. The first aircraft used in ASET is
the ICE configuration (provided by Lockheed
Martin Tactical Airframe Systems, LMTAS).
Distributed control effectors, developed at LaRC,
such as Passive Porosity and shape-change devices
(used to model synthetic jets) have been into
this simulation model. Advanced reconfigurable
control laws have been developed for this
aircraft under AVST/IRS program. Significance
This product will provide a immeasurable savings
in time for researchers bringing their ideas from
concept to real-time simulation. Virtually all
the simulation power, capability, and models of
the LaRC real-time simulation facility are
provided at the researchers workstation. The
unique interface ASET provides allows direct
movement of algorithms and data back to the
real-time facility from the researcher and
visa-versa from the real-time facility to the
researcher workstation. The best of both worlds
are linked. Future Plans ASET is intended to
be a long-term LaRC simulation capability,
therefore development and modification of ASET
should be a continuous process to meet the unique
changing requirements of leading edge research.
Direction of the tool development will be defined
by researcher requirements. More aircraft models
will be added to the ASET hangar as the LaRC
real-time simulation facility converts models
over to the LaSRS system. To date, a beta
version (0.8a) of ASET has been created that
provides a research modification capability
limited to whole subsystem replacement. ASET v1.0
will allow detail model parameter replacement.
Additional features may include, extension to
other CAD tool outputs besides Matlab.
