New Helicopter Proves Its Lifting Power
Designed to raise itself vertically and hover or fly forward at will, a new kind of helicopter showed promise in recent preliminary weight-lifting trials at Heston Aerodrome, England. When tethered by slack lines to stakes in the ground, it lifted front and rear wheels alternately under its own power. The lift is obtained from a three-bladed, horizontal propeller. Two long vanes or sweeps, resembling the tail feathers of a bird, are mounted at the rear to stabilize the odd craft. Full flight tests will be made soon and the designer is confident of success.
