Goddard Hoopskirt Rocket

摘要

--THE FOURTH TIME WAS THE CHARM j for Robert H. Goddard's "Hoopskirt Rocket," so named for its resemblance to the wire-frame skirts that had been popular among fashionable women around the time the rocketry pioneer was born, in 1882. He'd tried on three occasions beginning on July 18,1928 to get this, his second liquid-fuel rocket design, to fly, hoping merely for a successful demonstration of its rocket motor. But not until December 26 did the Hoopskirt clear the launch tower, flying 204.5 feet in 3.2 seconds over a field near Worcester, Massachusetts.
