Embodiment Construction

[0030] The following details the best presently contemplated modes of carrying out the invention. These descriptions are not intended to be limiting, but merely to illustrate the basic principles of the invention.

[0031] The injector ramjet propulsion system or engine may be a geometrically expandable ramjet engine having inlet, mixer, diffuser, combustor, and outlet nozzle elements or sections as commonly known , they are connected in sequence from the inlet to the outlet nozzle to form a whole. The engine can be of any shape to facilitate vehicle installation and facilitate the performance of each component over the engine duty cycle. As stated in the examples, a circular cross-section engine may be assumed, with a rectangular inlet cowling. The injector structure having the injector cavity therein may be mounted at the upstream end of the mixer section, normal to the longitudinal axis of the engine, to form an injector assembly. The injector element may be connected to...

Abstract

An injector-based engine, as exemplified in the injector ramjet (1), is an engine with an inlet (2), mixer (4), diffuser (5), combustor (6) and outlet ) conventionally reinforced ramjet element propulsion duct, allowing operation in the zero to hypersonic range. At the upstream end of the mixer (4), an injector assembly (50) is mounted in the fluid flow channel to form an injector (3). The injector assembly (50) has one or more injector rings with alternately offset injector exhaust nozzles (53) or slots to direct fluid towards the engine inner wall (14) or the engine longitudinal axis (9), respectively. ), thereby improving fluid mixing for shorter mixing zones. The supply of fluid to the injector exhaust nozzle (53) can be accomplished by flow pumps and other elements.

Description

technical field [0001] The present invention relates to a device for driving flight vehicles such as aircraft, spacecraft, missiles and rockets. The improved engine arrangement provides a combination of injectors and other engine components for efficient engine performance over a wide speed range. Background technique [0002] There are many techniques disclosed in the literature concerning the construction of ramjet engines and the use of injectors for various engines, including ramjet engines, which form an injector which works in conjunction with the ramjet cycle of the engine. However, there does not appear to be a practically viable jet engine other than the improved jet ramjet disclosed in US Patent 5,946,904 by the same inventor, corresponding to zero to hypersonic flight. [0003] Compared with conventional ramjet engines, the injector-type ramjet engine has advantages in terms of static thrust at sea level and engine thrust at various low-level flight speeds. For ...
