Title:
FOUR AERONAUTIC/ASTRONAUTIC TURBOFAN ENGINES
Document Type and Number:
WIPO Patent Application WO/2017/197544
Kind Code:
A1
Abstract:
Four aeronautic/astronautic turbofan engines, which are respectively a turbofan engine comprising an air inlet for introduction of oxygen-enriched air, a turbofan engine comprising two oxygen-enriched air inlets, a turbofan engine free of oxygen-enriched air, and a turbofan engine comprising an afterburner for introduction of oxygen-enriched air. Regarding the limited working altitude of an aeronautic turbofan engine, by providing an air-inlet oxygen-enriched air injecting assembly (1) and continuing to use the main structure of an existing aeronautic turbofan engine, a slightly modified main structure (2) is formed; by utilizing two types of regenerative cooling afterburners (3, 4, 5) having acoustic cavities and baffle plates, the aeronautic turbofan engine can be changed into an aeronautic turbofan engine capable of working within various altitude ranges. The four aeronautic/astronautic turbofan engines belong to the same series of aeronautic/astronautic integrated engines which can make full use of oxygen in the air for combustion, and can propel an aircraft to reach a flight altitude of 20-50 km and a flight speed of 2-5 Mach, or even more. These turbofan engines are applicable to a variety of aeronautic/astronautic integrated vehicles capable of being used repeatedly.
