    • An air intake (10) for a supersonic air-breathing flight vehicle is equipped with a means (110) for introducing or injecting air (90) in order to create predetermined regions of separated flow (160) and an attendant fluid shear layer (170). This shear layer (170) forms an aerodynamic boundary for the capture flow (150) with a profile determined and optimised by appropriate injection of air (90). The aerodynamic boundary so generated replaces mechanically moveable solid surfaces used to vary the geometry of prior-art intakes. Use of introduced or injected air (90) provides the advantages of a variable geometry, but with reduced weight and reduced mechanical complexity. In some embodiments, (15) the injection of air (90) has the effect of re-energising any ingested boundary layer (140), thus obviating the conventional requirement for a bleed system to provide boundary layer control.
    • 用于超音速呼吸飞行器的进气口(10)装备有用于引入或喷射空气(90)的装置(110),以便产生预定的分离流动区域(160)和伴随的流体剪切层(170) )。 该剪切层(170)通过适当地注入空气(90)确定和优化的形状为捕获流(150)形成空气动力学边界。 如此产生的空气动力学边界取代了用于改变现有技术摄入的几何形状的机械可移动的固体表面。 使用引入或注入的空气(90)提供了可变几何形状的优点,但重量减轻,机械复杂度降低。 在一些实施例中,(15)空气喷射(90)具有重新激励任何摄取的边界层(140)的作用,因此消除了渗流系统提供边界层控制的常规要求。

    • A pilot for a scramjet provides a flame front 28 whose arrival at the wall of the scramjet combustor 18 is delayed thereby reducing combustor 18 heat load By combining ?n-stream injection of fuel 19 with an interior pilot and a lean (fuel-poor) outer annulus, the bulk of combustion is confined to the scramjet combustor 18 center This concept, referred to as "core-burning," further reduces combustor 18 heat load One such pilot is for a two dimensional scramjet 40 effective to propel a vehicle This pilot includes a plurality of spaced apart struts 44 separated by ducts and a strut pilot 43 contained within each strut 44 A second such pilot is for an axisymmetric scramjet engine has, in sequence and in fluid communication, an air intake 16, an open bore scramjet isolator 50 and a scramjet combustor 18.

    • The ejector based engine is, as an example in an ejector ramjet engine (1), a propulsion duct having normal augmented ramjet elements of an inlet (2), mixer (4), diffuser (5), combustor (6) and exit nozzle (8) that allow operating velocities from zero to hypersonic. At the upstream end of the mixer (4) an injector assembly (50) is mounted in the fluid flow path to form an ejector (3). The injector assembly (50) has one or more injector rings which have alternatively offset injector exhaust nozzles (53) or slots to direct fluid toward the engine internal wall (14) or the engine longitudinal axis (9) respectively to improve fluid mixing for use of a shorter mixer section. The supply of fluid to the injector exhaust nozzles (53) may be by fuel flow pumps and other elements connected to injector chambers (55) in the injector ring or by an injector combustor (15) external to the mixer (4).

    • A modular power plant apparatus, and method of power plant assembly. An inlet air module (200) is provided on feet which are mounted on self centering rugged linear roller guides (204) which are linearly displaceable along a track (206). When the fuel-air mixing module is retracted along the roller track, the main engine housing (209) is pivoted on an engine stand, to position the output shaft upward. An exhaust bearing plate is removable from the main rotor housing, to allow the rotating element to be removed. When exposed, hot section elements can be inspected, repaired, and replaced.

This velocity/pressure regulation results in increased engine thrust and specific impulse performance. The diffuser (5) has guide vanes (19) to allow more rapid diffusion of the fluid flow.
