Design, Fabrication and Test of a Thrust Spoiler/Reverser System for a Low Cost, Expendable Turbojet

M-Dot, Inc. ("M-DOT") proposes to design, fabricate and test a thrust reverser system for low cost expendable turbojet engines. The system will be designed for application on the Sunstrand TJ-90 engine and will be configured for application on a bifurcated exhaust duct. The system will consist of the following: 1. Custom fabricated bifurcated exhaust duct for the TJ-90 engine. 2. Two pivoting vectoring ducts. One located at each exist. 3. Linkage and actuator for positioning the vectoring ducts. The Phase I program would accomplish the following: 1. Design and construction of a heavy wall thrust reversing system for ground test. 2. Bench testing to verify functionality of system. 3. Engine testing to verify performance and durability. 4. Compilation of design and test data. 5. Design layout of a flight weight system.
