Abstract

924,839. Rotary wing aircraft. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGEN KOMM.-GES.]. April 5, 1960 [April 7, 1959], No. 12016/60. Class 4. Control mechanism for rotorcraft is provided in which the vertical control of the rotorcraft is effected by axial displacement of a swash plate 18, 46 on the rotor shaft 47 by means of a sliding sleeve 44 controlled by an adjusting lever 88, in which horizontal control is effected by tilting the swash plate by means of a pair of tilting levers 68, 69, which are pivotally supported on adjusting lever 88, and in which the ends of the tilting levers act on the swash plate. Swash plate member 18 is universally mounted on sleeve 44 and is pivotally connected at 77, 76 to the tilting levers 68, 69, which are connected to the cyclic pitch control 1. Levers 68, 69 are in cross-wise arrangement and may be swivelled about a common bolt 70, which is supported by member 86 pivoted to adjusting lever 88, which is pivoted at one end to a projection 85 of sleeve 44 and at the other end to a rod 84, itself pivoted to a fixed point of the airframe. Lever 88 is connected to the collective pitch control 30 by rod 80 and lever 82. The linkage is such that operation of control 30 alters only the collective pitch and operation of control 1 alters only the cyclic pitch of the rotor. In another arrangement, Fig. 4 (not shown), the rotor shaft is between the cyclic pitch control arm and the tilting levers, the latter being side-by-side.
