Abstract:
1. A pulse detonation device, comprising: a pulse detonation combustor; a main inlet portion through which an oxidizer passes coupled to said pulse detonation combustor; a fuel supply portion coupled to said pulse detonation combustor which supplies a fuel to said pulse detonation combustor; a variable frequency ignition source coupled to said pulse detonation combustor to ignite a mixture of said fuel and said oxidizer provided from said main inlet portion; and a control system which controls at least one of a flow of said oxidizer, a flow of said fuel and said variable frequency ignition source at a plurality of operating conditions of said combustor, wherein a pressure pulse generated by a detonation within said pulse detonation combustor regulates said supply of fuel from said fuel supply portion by blocking the incoming flow of fuel; and wherein said control system continually increases or decreases an ignition frequency of said variable frequency ignition source in response to changes in said operating conditions.
