摘要:
Pulse detonation/deflagration apparatus (30, 30') for providing enhanced pressure wave operating frequency and/or magnitude, and methods of increasing the frequency or the magnitude of deflagration to detonation waves (37), are provided. A pulse detonation/deflagration apparatus (30, 30') can include a main/outer pulse detonation/deflgration actuator/engine (31) with multiple smaller internal combustion chambers or tubes (33) positioned inside the cavity of the main/outer actuator/engine (31) with each performing the function of individual pulse detonation/deflagration actuator/engines (31), The output pressure waves (37) created by the internal combustion chambers or tubes (33) can be utilized for propulsion or for controlling large scale flows, where needed.

An apparatus (100) for generating torque, the apparatus (100) comprising: a rotor hub (110) adapted for applying torque to a shaft; and a plurality of pulse detonation engines (120) adapted for impulsively detonating a plurality of fuel/air mixtures to generate thrust forces and applying the thrust forces to the rotor hub (110) to generate the torque.
摘要:
A small aircraft is disclosed having a propulsion system including a plurality of Pulse Detonation Engines (PDEs). The engines are arranged within the wings (2a) of the aircraft. The discharge nozzles (8) of the detonation tubes (7) of the detonation engines are provided at different areas of the aircraft and are differently oriented, so as to provide extra manoeuvrability along the three directions. The arrangement of the detonation tubes (7) within the wings (2a) reduces drag and hence the fuel consumption.
摘要:
A pulse combustion device has a number of combustors (22A-22E) with upstream bodies (28) and downstream nozzles (30). Coupling conduits (122A...) provide communication between the combustors (22A-22E). For each given combustor this includes a first communication between a first location upstream of the nozzle (30) thereof and a first location along the nozzle of another. There is second communication between a second location upstream of the nozzle (30) and a second communication between a second location upstream of the nozzle of a second other combustor and a second nozzle location along the nozzle (30) of the given combustor.
摘要:
A pulse detonation system (202) for a turbofan engine (200) including a fan assembly (212) and a turbine sub-system (230), which includes at least one turbine (232), is configured to create a temperature rise and a pressure rise within the turbofan engine and to generate thrust for the turbofan engine. The pulse detonation system includes a pulse detonation core replacement assembly (242) comprising at least one detonation chamber configured to detonate a fuel mixture. The pulse detonation core replacement assembly is positioned between the fan assembly and the turbine sub-system.

摘要:
A pulse detonation system (12) for a gas turbine engine (10) includes a core engine (30). The pulse detonation system is downstream from the core engine and is configured to create a temperature rise and a pressure rise within the gas turbine engine and to increase engine thrust. The pulse detonation system comprises a multi-staged pulse detonation augmentor (60) that comprises a predetonator (48) operable with at least a first operating stage wherein a less-than-stoichiometric fuel-air mixture is provided to the predetonator.
