Proposal Number: 07.04-1580B

Project Title: Minimum Frontal Area High-Thrust Engine

Technical Abstract (Limit 200 words)

SWB Turbines proposes to develop a minimum frontal area high thrust turbojet engine, ultimately suited for hypersonic shape vehicle propulsion. A diameter of 5" is achieved with a two-stage compressor, yielding 174 lbf thrust, SLS. Advanced aerodynamical design of the rotating components is achieved, resulting in a 10:1 pressure ratio operating regime, at full thrust. Innovations enabling a frontal area specific thrust of 8.9 lbt/in2 at low cost include high-efficiency aerodynamics with mixed flow two-stage compressor, uncooled net-shape cast combustor liner, high-work single stage mixed flow turbine with simple vaneless exhaust, and other innovations adapted from a line of micro-turbojet engine technologies. A unique team of SWB Turbines and Sundstrand Power Systems enables rapid engine prototyping, and the offering of an innovative, low-cost casting approach for the hot sections. Previously developed SWB turbojet engines SWB-3, SWB-4, SWB-5) for similar applications have proven to be very reliable and have exceeded specifications, logging many hours in both test cell and unmanned aerial vehicles. Previously developed Sunstrand engines include the TJ-50 turbojet, TPR-80 turboprop, and the ATR-120 air-turbo-rocket engine. Sundstrand also provides a cost share initiative to the Phase II effort.

Potential Commercial Applications (Limit 200 words)

A strategic commercial plan developed by SWB Turbines, included in part in this proposal, identifies a host of commercial users, including those that have provided letters of interest outlining Phase III commitments, and vehicle integration planning sessions. Use includes unmanned aerial vehicles for Teledyne-Ryan, Boeing Hypersonics Division, Naval Air Systems, Accurate Automation Corporation, and others. Vehicles may be used for reconnaissance, DOD missions, earth observation, SSTO vehicle research, and advanced high-speed vehicle testing.
