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).

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.

Book excerpt: Investigations were made to study the water landing and certain ground-surface landing characteristics of a Gemini spacecraft model. The water landing experiments were made by simulating paraglider and parachute letdowns with two 1/6-scale model configurations. Parameters included various combinations of attitude, horizontal speed, vertical speed, and landing skids extended and retracted. Investigations were made in calm water and in waves. The paraglider landings at horizintal speeds of 65 feet per second (19.8 m/sec) and above resulted in a noseover or tumbling shortly after initial water contact. The maximum longitudinal acceleration of the model in calm water was about 14g units, and the maximum angular acceleration was 66 radians per second squared. In the Parachute landings with the heat shield forward the model skidded along the water surface on the heat shield. Parachute landings with the small end forward resulted in behavior similar to that of the paraglider landings.
