Abstract
701,504. Fluid-pressure servomotor-control systems; valves. NORTHROP AIRCRAFT, Inc. March 29, 1949 [April 27, 1948], No. 8502/49. Class 135. [Also in Group XXXIII] The subject-matter of this Specification is substantially the same as that described in Specification 701,092, the only difference being that an embodiment is added applicable to the operation of drag rudders mounted on flaps disposed in the trailing edges of the aircraft wing tips. In the added embodiment, Fig. 6, the cylinder is fixed and the piston movable and operably connected through its rod 154 to an upper flap 150 of the drag rudder 6. A lower flap 151 is operable through crossed cables 161 passing over quadrants 160 secured to the flaps. The valve spool is restored to its neutral position relative to the sleeve by a follow-up rod 182, lever 178 and rod 179. Specification 629,714, [Group XXXIII], also is referred to.
