SwRI
provides Operational Flight Program development to
support both current and future upgrades to the
Turbine Engine Monitoring System / Airborne Data
Recorder (TEMS/ADR) avionics LRU in accordance with
ISO 9001:2000 procedures. SwRI’s proven processes
have resulted in efficient and cost-effective
software engineering development and simulation
capabilities that allow us to successfully design,
test, integrate and perform formal qualification
tests in preparation for aircraft flight test. |
Aging equipment and machinery may become outmoded,
unserviceable or unable to satisfy today's high-performance
requirements. To modernize or replace outdated equipment, Southwest
Research Institute (SwRI) provides a wide range of retrofit
engineering services, including:
-
Redesign of mechanical, electrical and software
systems, subsystems or components
-
Replacement of outdated technology with modern
and innovative solutions
-
Increased mean-time-between-failures (MTBF) of
high-failure items
-
Development of efficient and effective in-house
diagnostic and
maintenance capabilities
-
Improvement of system or subsystem reliability
and maintainability
Retrofit
Engineering Applications
Drawing on SwRI's multidisciplinary capabilities, SwRI engineers solve
problems associated with requirements for:
-
Development of
technical data package
-
Drawings or
technical data ownership
-
Enhanced
functionality of components or systems
-
Establishment
of in-house maintenance capabilities
-
Identification
or qualification of new vendors

Fighter
aircraft are prepared to respond to airborne threats
detected over the United States and Canada by the
U.S. Air Force Atmospheric Early Warning System (AEWS).
Radar consoles used by the AEWS contain electronic
components, such as the circuit board shown, that
are becoming increasingly hard to repair or
replace. For the AEWS system, SwRI provided Form,
Fit, Function (FFF) replacements of Circuit Card
Assemblies (CCAs – both analog and digital),
keyboards, trackballs, printers and power
supplies. (Fighter aircraft photo courtesy U.S. Air
Force by Staff Sgt. Bennie J. Davis.) |

Aircraft Systems Support
To support the SwRI mechanical redesign
program, engineers may use the following equipment, software
applications and procedures:
-
Coordinate measuring
machines to determine dimensions
-
Optical, scanning and auger
microscopes to provide metallurgy information
-
Pro/ENGINEER™ and Solidworks® to
create virtual prototypes
-
ANSYS™, Solidworks® and COSMOS®
to provide stress and thermal modeling
-
Stereolithography to produce
rapid prototypes
-
Temperature, humidity, vibration
and electromagnetic interference and compatibility (EMI/EMC) tests
to evaluate prototypes
SwRI’s
electrical redesign efforts may include:
-
DxDesigner® to capture schematics
-
MATLAB® and Simulink® to model
control system and DSP functions
-
DXSIM® to simulate analog
electrical circuits
-
ModelSim® to simulate digital
circuitry and programmable logic
-
Synplify® to synthesize VHDL or
Verilog hardware descriptions Xilinx® ISE&trade to generate programmable
logic files for Field Programmable Gate
Arrays (FPGA)
-
Hyperlynx® to perform signal
integrity analysis
-
PADS® to lay out printed circuit
boards
-
Automatic test equipment (ATE)
and test program sets (TPS) to support new components
