Abstract: An improved gas generator apparatus having a compressor, a combustor, and a turbine having a turbine rotor coupled by a rotor shaft to the compressor rotor of the compressor. The combustor is spiral shaped and positioned between the compressor and turbine which allows the direction of flow of air or working gas to remain substantially unchanged from the compressor to the turbine, while maintaining a compact configuration. In operation, air drawn into the compressor is swirled circumferentially and pressurized by the compressor, and then delivered into a combustion chamber while it is being swirled. Air is expanded in the combustion chamber as it is swirled in and along the spirally shaped expansion chamber tube and then flows as a working gas into the turbine in which the gas drives the turbine rotor while the gas is still being swirled in the same direction. The air or working gas, therefore, maintains a swirling flow in one direction from the compressor to the turbine.

Abstract: A relatively low drag, completely free-flying, tubular vehicle comprises a body that defines a leading edge and a trailing edge and includes an external surface and an internal surface each extending from the leading to the trailing edge. The internal surface has an axially converging upstream section extending from the leading edge to a discontinuity that constitutes a throat in the vehicle. The internal surface also has an axially diverging downstream section extending from the throat to the trailing edge. The internal surface is configured to enable introduction and mixing of fuel into an airstream flowing therethrough, and to generate a shock wave when in flight. The shock wave is of such magnitude and direction as to create a hot spot that subsequently causes ignition and combustion of the fuel-air mixture. The combustion causes formation of a detonation bubble and migration of the associated wave front upstream to stabilize slightly downstream of the throat.
