This book was released on 1960 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation has been made to determine the landing characteristics of a conical-shaped reentry capsule by using torus-shaped air bags for impact alleviation. An impact bag was attached below the large end of the capsule to absorb initial impact loads and a second bag was attached around the canister to absorb loads resulting from impact on the canister when the capsule overturned. A 1/6-scale dynamic model of the configuration was tested for nominal flight paths of 600 and 900 (vertical), a range of contact attitudes from -250 to 300, and a vertical contact velocity of 12.25 feet per second. Accelerations were measured along the X-axis (roll) and Z-axis (yaw) by accelerometers rigidly installed at the center of gravity of the model. Actual flight paths, contact attitudes, and motions were determined from high-speed motion pictures. Landings were made on concrete and on water.

This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical and experimental investigations were made to determine the landing characteristics of a re-entry spacecraft equipped with a verticalcylinder air bag for impact load alleviation. Assuming a rigid body and isothermal air compression and expansion, computations were made to determine accelerations for a landing on concrete from a flight-path angle of 90 degrees (vertical flight path) at a contact attitude of 0 degrees. Two models (1/6 and 1/2 scale) of the air-bag system were tested. A 1/6-scale dynamic model of a spacecraft--air-bag configuration proposed for manned re-entry was landed on concrete, on sand, and in calm water from various flight paths for a range of contact attitudes. Reasonable agreement between computed and experimental data indicates that the scaling technique developed is satisfactory for prediction of fullscale characteristics from model tests with air bags in atmospheric environment. The maximum accelerations obtained during landings on sand were about 11g along the X-axis and about 8g along the Z-axis. The maximum accelerations obtained during landings in water were about 10g along the X-axis and about 6g along the Z-axis. (Author).
