Book Effects of Reynolds Number and Body Corner Radius on Aerodynamic Characteristics of a Space Shuttle type Vehicle at Subsonic Mach Numbers

Download or read book Effects of Reynolds Number and Body Corner Radius on Aerodynamic Characteristics of a Space Shuttle type Vehicle at Subsonic Mach Numbers written by Leland Howard Jorgenson and published by . This book was released on 1972 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Static aerodynamic forces and moments were measured to study the effects of Reynolds number and body corner radius on the aerodynamic characteristics of a straight wing space shuttle orbiter at subsonic speeds. A 0.02-scale model was tested at Mach numbers from 0.3 to 0.9 and Reynolds numbers from about 600,000 to 3 million, based on body width. The body alone and the body with its wing and horizontal tail attached were tested at angles of attack from 35 to 75 degrees. The effects of rounding the body corners at the junctures connecting the bottom and sides were investigated for corner radii from 0 to 8.5 percent of the body width. At low subsonic Mach numbers (free stream Mach number approximately equal 0.3) the aerodynamic characteristics are affected significantly by changes in Reynolds number and body corner radius. With increase in Mach number to free stream Mach number = 0.9 the effect of Reynolds number seems to vanish, but a significant effect of body corner radius remains.

Book Comparison of Space Shuttle Orbiter Low Speed Static Stability and Control Derivatives Obtained from Wind Tunnel and Approach and Landing Flight Tests

Download or read book Comparison of Space Shuttle Orbiter Low Speed Static Stability and Control Derivatives Obtained from Wind Tunnel and Approach and Landing Flight Tests written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-13 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the 8 foot transonic pressure tunnel to obtain wind tunnel data for comparison with static stability and control parameters measured on the space shuttle orbiter approach and landing flight tests. The longitudinal stability, elevon effectiveness, lateral directional stability, and aileron effectiveness derivatives were determined from the wind tunnel data and compared with the flight test results. The comparison covers a range of angles of attack from approximately 2 deg to 10 deg at subsonic Mach numbers of 0.41 to 0.56. In general the wind tunnel results agreed well with the flight test results, indicating the wind tunnel data is applicable to the design of entry vehicles for subsonic speeds over the angle of attack range studied.
