The development of the Detonation Cycle Gas Turbine engine has proceeded by way of the sequential design, construction, development and testing of
multiple prototypes. These have proven the practicality of the DCGT engine.
First Feasibility Prototype, April 1987
First Upscale Prototype, December 1989
First Low-Inertia Prototype, April 1993
Fourth Engineering Prototype, December 1997
540 hp Prototype, April, 2007
Videos of Prototypes 2, 3 and 5 are available below.

TTE received delivery of the 540hp Prototype engine from Cost Cast, Inc. in March 2006. Robert Scragg of Alpha continued the building and outfitting of this prototype at our new Demonstration Facility. The fuel and ignition systems were fitted as well as other hardware and the electrical system required prior to testing. Custom Tube Products Inc. will work with Alpha and TTE to build the exhaust manifolds for testing purposes.
Pictured below are conceptual renderings of Prototype Number 5. The renderings were produced in the program CATIA that was also used to design the Airbus 380 and the Boeing 787.
