Embodiment Construction

[0019] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] The invention provides an air turbine ramjet combined engine, such as figure 1 As shown, the air turbine ramjet and the ramjet including the common intake port 1 and the common exhaust nozzle 5, the air turbine ramjet and the ramjet are arranged in parallel up and down, and the shared intake port and the exhaust nozzle can reduce the The effect of small air resistance.

[0021] An air intake guide 2 is arranged on the pipe of the air intake 1 . The air inlet guide 2 is used to turn and close the inlet of the air turbine ramjet when the air turbine ramjet starts at a low speed, so as to communicate the air inlet 1 with the inside of the air turbine ramjet; At Mach 3, turn and close the air turbo ramjet inlet to connect intake 1 with the ramjet interior and increase the speed to Mach 6.

[0022] The air inlet g...

Abstract

The invention discloses an air turbine ramjet combined engine, which comprises an air turbine ramjet and a ramjet which share an air inlet and a common tail nozzle, and an air inlet guide is arranged on the pipe of the air inlet; the air inlet guide , used to turn and close the inlet of the ramjet when the engine is started at low speed, so as to communicate the intake passage with the interior of the air turbine ramjet; it is also used to turn and close the air turbine ramjet when the speed of the air turbine ramjet is greater than or equal to Mach The inlet of the engine to connect the intake with the interior of the ramjet and increase the speed to Mach. It solves the problem that neither of the existing two power systems can fully meet the power requirements of modern warfare on weapon systems at super-sonic speed, super-high altitude, high maneuverability and high-altitude domain.

Description

【Technical field】 [0001] The invention belongs to the field of rocket carrier power systems, and in particular relates to an air turbine ramjet combination engine and a working method thereof. 【Background technique】 [0002] The Air Turbine Ramjet (ATR) is a propulsion system that combines a conventional fan and a turbine with a rocket-like combustion chamber. It combines the characteristics of a rocket engine and a ramjet engine, and its performance is between a turbojet engine and a rocket engine. The expansion of the high-pressure high-energy gas produced by the gas generator can be realized by a turbine device much simpler than that of a traditional turbojet cycle engine, and air boosting can also be realized by a much simpler compressor device than a traditional turbojet cycle engine. The outstanding feature of ATR is that it actively inhales air, can generate thrust at zero speed, and its working range covers the altitude range from the ground to the adjacent space. C...
