When the rocket is launched, its engine and the auxiliary fuel will be ignited at the same instant. The trapped combustion gases will produce a pressure of 500 lbs. per sq. in. that will drive the rocket upward with 3,600,000 lbs. of thrust and about 35 Gs of acceleration. It should reach the end of the tube in 1,205 sec. Air pressure will open the doors to let it pass, and it will pop out with the respectable speed of 1,000 m.p.h. Only 2,500 lbs. of its own fuel will have burned, and it will...
...tough as combat operations, and sometimes men get hurt or killed." In preparing for the Eglin show, one did. Captain Charles G. Lamb Jr., 31, of Indianapolis, died when his F-10s disintegrated at 2.000 ft. as he practiced a supersonic bomb pullout with a force of 4.25 Gs...
...planned impact point was 200 miles east of Bermuda, where an array of ships and aircraft waited anxiously. Down curved MA-4, trailing flames, its simulated astronaut stoically suffering 7.8 Gs of deceleration. The tough 6-ft. drogue chute opened first; then the main chute opened and lowered MA4 gently into the Atlantic, 161 miles east of Bermuda and only 39 miles off target. For a vehicle that had been traveling at 17,519 m.p.h., this was good shooting indeed. Aircraft spotted the capsule at once, and the destroyer Decatur raced to pick...
...Grissom's craft began to push against the top of the atmosphere, the Gs rose-to ten, then to a fearful 10.2-and communication dimmed a little, but never wholly stopped. Grissom reported clearly at 65,000 ft. that the Gs were much lower now. Then, with the capsule at 40,000 ft., the men on the Randolph and the choppers strained to catch their first glimpse of it. Automatically the small, tough drogue parachute opened at 21,000 ft., checking the capsule's falling speed. One minute later, the great, striped, red-and-white main parachute (with...
...their cheers when they heard that Shepard was on his way, waited in silent expectation as he made his lonely flight. From time to time an announcer reported his progress; then Shepard's voice itself came over the loudspeaker. It was not clear. He was descending, and the Gs of re-entry were pressing him hard. Every man on the deck scanned the sky. When Freedom 7's big orange-and-white parachute popped open at 10,000 ft., the Lake Champlain came alive with cheers once more. "Damn!" the sailors shouted. "Marvelous...
