1 Introduction Hypersonic vehicles with airbreathing propulsion systems provide
an efficient means for access to space because the oxidizer required by the
propulsion system can be supplied by the earth's atmosphere for much of the
A GENERAL PURPOSE DIGITAL SYSTEM FOR ON - LINE CONTROL OF AIRBREATHING PROPULSION SYSTEMS by Dale J. Arpasi , John R. Zeller ,
and Peter G. Batterton Lewis Research Center SUMMARY Control development
In the airbreathing propulsion mode the engine uses the atmosphere for the
oxidizer . The inlets are of a two - dimensional , multiramp design . These inlets
will require variable geometry to improve vehicle aerodynamics and improve
airflow to ...
This renewed interest has led to an expansion of research related to high speed airbreathing propulsion, in particular, the supersonic combustion ramjet, or
scramjet. The history is briefly traced of scramjet research in the U.S., with
Airbreathing propulsion has come to fulfill a vital need in human activities , in
transportation , and in defense and therefore has a developing future so long as
air can be used effectively in the engine without affecting the quality and
existence of ...
In the following , it will be discussed what the future potentialities of airbreathing
jet propulsion systems probably will be . attractive approach for improving the
propulsive efficiency . The first fan jets had a relatively small bypass ratio of about

Influence of Airbreathing Propulsion Art And although airbreathing to much
higher speed than Mach 12 may be useful for aerospace planes that use
chemical propulsion alone , it would be counterproductive when fusion - electric

This work describes the physical and operating characteristics of a range of modern gas turbine engines. Ramjets, scramjets and pulsejets are included in the discussion, taking account of real gas effects and losses. Environmental issues are also incorporated.
By this we mean that the first step could be a two stage space transportation
system with an hypersonic engine of the turboramjet family ; following the
acquisition of experience with the hypersonic flight and airbreathing engine , it
will be ...
As a recent option , a design project can be added that uses both the on - design

Annotation Leading researchers provide a cohesive treatment of the complex issues in high-speed propulsion, as well as introductions to the current capabilities for addressing several fundamental aspects of high-speed vehicle propulsion development. Includes more than 380 references, 290 figures and tables, and 185 equations.
Turning all this around to a positive orientation , it will be noted that the SERJ
engine had its origins in advanced highly - reusable launch ... To date , airbreathing propulsion has exclusively served the large , long - existing aviation
Part of the ASTP is the 3rd Generation Access to Space, which NASA refocused
beginning in FY02 to airbreathing propulsion vehicles, and called the effort the
Hypersonics Investment Area (HIA). Within the HlA, are six projects: Airframe ...
The airbreathing and rocket elements are each tailored such that they optimally
interact , both physically and functionally . This propulsion integration approach
provides several distinct engine operating modes to match engine thrust
