The Cooperative Unmanned Systems Laboratory (CUSL) is a multi-disciplinary research lab at the University of Kansas (KU) that focuses on the design, development, and testing of teams of unmanned systems for cooperative sensing and cooperative control missions. The research objectives of CUSL include autonomous system development, gust/wake sensing and wind soaring using UAVs, design of cooperative sensing and estimation algorithms, and networked cyber-physical systems.

The Adaptive Aerostructures Laboratory (AAL) maintains unique capabilities supporting the design, fabrication and testing of aerospace structures with adaptive materials. Unlike conventional materials, adaptive materials change some property as a function of an applied control signal or stimulus. The AAL maintains a range of stocks of piezoelectric, electrostrictive, shape-memory-alloy, magnetostrictive, magnetorheological, and other adaptive materials and processing equipment. In addition to supporting work with adaptive materials, the AAL has generated many aerospace “firsts” in subscale uninhabited aerial vehicles, morphing aircraft, missles and munitions. It is currently host to a unique ballistics laboratory where guided bullets and cannon shells are being designed and tested in the 40mm x 10m and 20mm x 5 m gas guns. More than 50 subscale aircraft are housed in the 1200+ sq. feet facility as well as 9 grades of graphite-epoxy composites, 4 grades of Kevlar, composite cure oven, diamond saws and precision post processing machines.

In the Computational Thermal Fluids Laboratory we develop state-of-the art CFD algorithms and tools on modern computer platforms such as CPU and GPU clusters. In addition, we apply these tools to solver challenging fluid dynamics problems such as flow over high lift configurations, helicopters, flow inside jet engines, noise generated by moving bodies, to name just a few. Our research has been supported by AFOSR, DOE, NSF, DARPA, ARO, NASA, ONR. 

The Acoustic Reverberation Suite includes two adjacent, acoustically reverberant (“echoing”) rooms with a 4-foot by 8-foot aperture (“window”) between them.   The suite is designed to measure Transmission Loss (TL) for room or vehicle walls and Absorption Coefficients of sound-absorbing materials used in walls or interior furnishings.  Flat or slightly curved panels are inserted into the aperture to measure the TL when sound—generated and measured in the south room—is transmitted to the north room.  The difference in the measured sound pressure level (SPL) is resolved as the TL on which the panel Noise Isolation Class (NIC) rating is based.  Alternatively, the acoustic absorption of objects placed in one of the rooms may be measured by comparing the room reverberation time with and without the test objects.  This facility is currently primarily used to devise and evaluate alternative test methods associated with noise reduction and for testing the noise reduction qualities of panels fabricated with new materials and/or new noise reduction schemes.  The types of panels to be evaluated include aircraft fuselage side-walls and new building walls.  Coefficients of absorption will be measured for various architectural materials including fabric used for variable reverberation control in auditoriums and similar spaces.

Garrison Flight Research Center (Airport Hangar #1)

The Garrison Flight Research Center (GFRL) was established in 2004 with the renovation of the existing 18,000 square foot university hangar. The GFRL, now upgraded to 22,000 square feet, has a classroom, machine shop, electronics shop, offices, an AST 4000 fixed base simulator and hangar space for several aircraft. These provide resources for developing intelligent vehicle systems for the flight research of both piloted and uncrewed air vehicles. Additional shop and assembly space, along with a propulsion test cell, are available in an adjacent building, the KUAE “Hawkworks”.​

The Garrison Flight Research Center houses the department’s Cessna 172 Skyhawk and Cessna 182 RG. The Cessna 172 is used both for transportation and research, while the Cessna 182 is dedicated to flight research activities. The Cessna 182 is specifically configured to accommodate in-flight test instrumentation. 

In addition, KUAE has recently invested in an AST 4000 Fixed Base Simulator, produced by American Simulation Technology. This flight simulator is PC based with programmable LCD Instrument Panels and programmable digital aircraft dynamic models. The “vehicle” can accommodate our experimental autopilot module, and offers an out the window projection system and built-in weather and turbulence effects with a programmable control loader. Student designed vehicles may be entered in the flight characteristics module such that vehicles may be “flown” and experienced by the design team.

The Structural Load Frame is a 35' x 35' test bed located in the Garrison Flight Research Center hangar at the Lawrence Airport. This test bed is capable of point loads up to 4,000 pounds. Associated with the test floor is a steel frame capable of static testing full-scale aircraft as large as a Raytheon Baron. The frame is also used to conduct acoustic testing on full-scale aircraft fuselage components.

The Department of Aerospace Engineering maintains a research machine shop with two milling machines, a lathe, sheet metal break and shear equipment, band saws and drill presses. In addition, the School of Engineering maintains a fully-equipped machine shop with multiple milling machines, surface grinders, vertical and horizontal band saws, drill presses, welding equipment, and a paint booth. New acquisitions include a Stratasys Prodigy fused deposition modeling rapid prototyping center and a computer numerically controlled (CNC) mill with five axes of motion and 48" x 20" x 20" travel in translational axes.

Airport Hangar #2
