Abstract

8290. Pohl, R. April 6. Screw propellers.-Relates to propellers for aerial machines with yielding blades, and consists in constructing them of rubber or rubber composition so that they are limp when not in use. An insertion c of some toughening but not rigid material may be inserted in the blade b, which is clamped between the two parts of the boss. In a modified form the blade is adapted to be inflated by gas.
