The SEEK EAGLE F-15E Mixed Loads Certification test program was created and funded in response to the United States Air Force (USAF) Air Combat Command's (ACC) request to certify new air-to-ground (A/G) configurations and weapon release sequences on the F-15E. The primary concerns which required flight testing were store separations from the wing pylon and conformal fuel tank (CFT) stations as well as the structural compatibility of new weapon configurations. Safe separation testing consisted of 35 missions that included weapon releases and captive carriage of most of the conventional stores in the USAF inventory. A total of three captive compatibility flight profiles (CFPs) were flown with GBU-10/12 Paveway II laser guided bombs (LGBs) and the M-129 leaflet dispenser. Mixed Loads test results are currently being reported on by the SEEK EAGLE Program Office and the 40th Flight Test Squadron at Eglin Air Force Base, Florida.

The disposal of waste lubricants and fuels at U.S. Air Force and Navy facilities is discussed in this paper. The waste products covered include: synthetic turbine oil, aviation piston engine oil, hydraulic fluids, and contaminated JP-4 and JP-5. Technical feasibility and the economics of various disposal alternatives, including use as a fuel, rerefining, and recycling, as well as entrepreneurial outlets are presented. Waste lubricants and fuels handling, classification, and storage are also discussed in connection with the disposal problem.

The engines used to power small unmanned aerial systems are often modified commercial products designed for use by hobbyists on small model aircraft at low altitude. For military applications, it is desirable to fly at high altitudes. Maintaining power from the engine at the reduced ambient air pressures associated with high altitudes requires some method of increasing air delivery to the intake manifold. Conventional turbochargers and superchargers are typically very inefficient for the low mass flows associated with small engines. Due to its unique characteristics, a pressure wave supercharger (PWS) can avoid many scaling-related losses. This project designed a small-scale PWS for turbo-normalization of a Brison 95 cc two-stroke engine for a small unmanned aerial vehicle. A larger PWS called the Comprex®, designed by Brown Boveri Company, was simulated using a quasi-one-dimensional Computational Fluid Dynamics (CFD) code developed at the NASA Glenn Research Center.
