Abstract

413,184. Propelling aircraft. DORNIER, C., Friedrichshafen, Germany. Nov. 24, 1933, No. 32944. Convention date, Feb. 2. [Class 4.] In helicopters in which the blades are driven by the reaction effect of a driving medium issuing from nozzles at the tips of the blades, the nozzles are arranged rotatably about the longitudinal axis of the blade. As shown in Figs. 1 and 2, the reaction nozzles 4, 5 are rotatably mounted at the wing tips and are connected to shafts 8, 9 having bevel wheels 10, 11 gearing with a bevel wheel on the shaft 13. In operation, the shaft 13 is rotated at the same speed as the wings to maintain the nozzles in their tangential positions, decrease or increase of the speed of the shaft 13 relatively to the wing causing a rotation of the nozzles about their axes and serves as a means of controlling their angular position. In a modification, the shafts 8, 9 are replaced by a single shaft having a bevel wheel engaging with the bevel wheel on the shaft 13 so that any rotation of the nozzles causes them to move out of the plane of the wing in opposite directions. Fig. 7 shows an arrangement whereby the nozzles may be turned in any direction independently of one another. A shaft 28 and sleeve 23 are provided with toothed quadrants 27, 22 gearing with bevel gears 26, 21 on the shafts 25, 20 of the nozzles 24, 19.
