SATURDAY REVIEW Vol. 33, No. ?, p. 21 Saturday, Sept. 23, 1950 IN A SAUCER FROM VENUS by Roland Gelatt But is it from Venus? This draughtsman's conception of a flying saucer shows a helicoptered transparent metal turret with a series of blades flush with the disc's surface. The disc is rotated on the ground at relatively high r.p.m., then the pitch is turned on in the blades, propelling the air from the upper surface of the disc to the lower. This results in decreased pressure on the top and an increase beneath, lifting the disc in a vertical position to any desired altitude. In flying, the disc would be tilted slightly nose down, causing the air underneath to slip backward and propelling the disc forward. |
