Analysis of scattering for the flow field of a hypersonic flight vehicle

Abstract: A hypersonic flight vehicle flow filed was simulated by adopting the 7species chemical model.Based on the flow field,apiecewise linear current density(JE)recursive convolution finite-difference time-domain(PLJERC-FDTD)algorithm was applied to calculate the vehicle backward RCS and bistatic RCS in P,L-band.The effects of incidence wave frequency and bistitic angle on the radar cross section(RCS)were analyzed.The results illustrate that in most range of calculation frequency,the backward RCS of plasma sheath flow field is smaller than that of the vehicle itself.Simultaneously,the angle of attack has an influence on the RCS.When the incidence wave frequency is close to the plasma frequency,the plasma sheath can improve the vehicle stealth performance.On 1GHz frequency,the RCS of the plasma sheath flow field and vehicle itself varies with the bistatic angle and the bigger one occur alternately without a good rule.

British Rocket and Ramjet Engines: A Survey of Work to Date in This Important Field

Abstract: ROCKET and ramjet engines have not the universal application that gas turbines command and possibly on this account they have not had, until recent years, the development effort which gave such amazing results in turbine powered aircraft Nevertheless, they have demonstrated quite dramatically in various parts of the world that they are power plants to be reckoned with In Great Britain, their value for aircraft was appreciated somewhat belatedly and events have since decreed that the promise they showed should be smothered before it could become a vital fact On the other hand their importance for missiles was realized at the conclusion of the 1939–45 war, but again they were not encouraged on anything like the scale that present events show would have been justified Because of this lack of encouragement, British rockets and ramjets, instead of leading the world, as do gas turbines, are struggling hard to provide a modest rate of progress

Flying and Handling Qualities

Abstract: This chapter explores the flying and handling qualities of an aeroplane. These qualities are those properties that govern the ease and precision with which the aeroplane responds to pilot commands in the execution of the flight task. Although these rather intangible properties are described qualitatively and are formulated in terms of pilot opinion, it becomes necessary to find alternative quantitative descriptions for more formal analytical purposes. The flying and handling qualities of an aeroplane are, in part, intimately dependent on its stability and control characteristics. This includes the effects of a flight control system when one is installed. The stability and control parameters of an aeroplane are commonly used as indicators and measures of the flying and handling qualities. So, the object of the chapter is to introduce, at an introductory level, the way in which stability and control parameters are used to quantify the flying and handling qualities of an aeroplane. Various examples have been explained throughout the text for better illustration of the subject. The chapter classifies the aeroplane and defines its flight phase. It emphasizes on the importance of the design of an aeroplane and thus a designer designs to achieve the highest level of flying qualities whereas, an evaluator confirms that this gets accomplished.
