Research Institution
The Nutating Disk Engine is a new technology with significant advantages, and multiple potential military and commercial applications. Development work has focused on a dual-disk version of the engine, including a demonstrator prototype. Second-generation prototype is currently in development. This DARPA program provides an opportunity design a single-disk version. Development work to date has lead to the conclusion that a single-disk version is not only feasible, but desirable. The single-disk Nutating Engine offers several advantages including improved power density, reduced component count, direct routing between compressor outlets and prechamber, and the elimination of coupling hardware. The proposed Meyer Nutating Disk Engine will be a single disk engine designed to produce an output of 8-10 Hp at 4,500 rpm, and run on heavy fuel. The compact size packages this engine within a 5.75” diameter and 5.95” overall length. The engine weighs 5.6 lbs. with a projected power density of 1.46 Hp/lb. Heavy fuel operation allows it to operate efficiently at reduced rpm and light loads. Quiet operation is also expected. The single-disk engine will be designed and analysis performed during Phase I, ultimately leading to the production of a demonstration engine, paired with a generator, during the Phase II effort.
