ISBN: 0323972233
Category : Technology & Engineering
Languages : en
Pages : 248
Book Description
Aerodynamic Heating in Supersonic and Hypersonic Flows: Advanced Techniques for Drag and Aero-heating Reduction explores the pros and cons of different heat reduction techniques on other characteristics of hypersonic vehicles. The book begins with an introduction of flow feature around the forebody of space vehicles and explains the main parameters on drag force and heat production in this region. The text then discusses the impact of severe heat production on the nose of hypervelocity vehicles, different reduction techniques for aerodynamic heating, and current practical applications for forebody shock control devices. Delivers valuable insight for aerospace engineers, postgraduate students, and researchers. Presents computational results of different cooling systems for drag and heat reduction around nose cones Explains mechanisms of drag reduction via mechanical, fluidic, and thermal systems Provides comprehensive details about the aerodynamics of space vehicles and the different shock features in the forebody of super/hypersonic vehicles Describes how numerical simulations are used for the development of the current design of forebody of super/hypersonic vehicles
The Effects of Aerodynamic Heating and Heat Transfer on the Surface Temperature of a Body of Revolution in Steady Supersonic Flight

Book Description
An approximate method for determining the convective cooling requirement in the laminar-boundary-layer region of a body of revolution in high-speed flight was developed and applied to an example body. The cooling requirement for the example body was determined as a function of Mach number, altitude, size, and a surface-temperature parameter. The maximum value of Mach number considered was 3.0 and the altitudes considered were those within the lower constant-temperature region of the atmosphere (40,000 to 120,000 ft). The extent of the laminar boundary layer was determined approximately at each condition as a function of the variables considered.

Author: Calculation of Surface Temperatures in Steady Supersonic Flight

Category : Aerodynamic heating

Pages : 34
Book Description
Surface temperatures were calculated for bodies in steady supersonic flight at Mach numbers from 2 to 10 and for altitudes from 50,000 and 200,000 feet and emissivities from 0 to 1. The importance of the effects of radiation and convection was determined. It was found, under the assumption of an isothermal atmosphere, that the gain of heat from the air by convection decreases at constant Mach number as the altitude is increased. Equilibrium between convection and radiation is established at temperatures that that consequently decrease as altitude is increased. In general, therefore, at sufficiently high altitudes the surface temperature is considerably less than the stagnation temperature. At a Mach number of 8, for example, the stagnation temperature is 4800 degrees F absolute and the equilibrium surface temperature for an emissivity of 0.5 is 3800 degress F absolute at 50,000 feet and decreases to 1350 degrees F at 200,000 feet.
