Title: Aircraft control system
IPC: G05D1/06
Filed: 1964-05-07
Abstract: 1,065,865. Radio navigation. SPERRY RAND CORPORATION. May 7, 1964 [May 10, 1963], No. 19003/64. Heading H4D. An aircraft landing system for controlling the aircraft during flight down an independently defined glide path includes a generator producing signals representing the actual flight path, sensing means for determining when the actual flight path differs from the glide path, means receiving the actual flight path signals and responsive to the flight-path-error sensing means to produce output signals which, when the flight path error is insignificant, represent the actual flight path but when the flight path error increases are reduced, and a memory device to which the output signals are applied so that it stores an average value which represents a flight path substantially coinciding with the glide path. In one embodiment (Fig. 3) a memory device (16, Fig. 1) in a known arrangement is replaced by a storage capacitor (20) in series with a relatively low resistance (22) and a normally-closed switch (24) which is opened by a relay (28) whenever the aircraft departs from an I.L.S. glide path. In the preferred embodiment (Fig. 4) a rate-of-descent signal from a path computer is applied to a first comparison circuit (30) the output of which feeds a second comparison circuit (32) controlling a first servomotor (34) driving a generator (36) and the wiper of a first potentiometer (38). The output of the generator is applied across a second potentiometer (40) the wiper of which affords a rate feedback signal input to the second comparison circuit. Thus the gain, and hence time constant, of the loop including the comparison circuits and first potentiometer depends on the position of the wiper of the second potentiometer, and the wiper of the first potentiometer carries a signal representing the memorized path signal. The glide slope receiver output is differentiated and rectified to provide a signal representing the rate at which the craft is moving to and from the I.L.S. glide path; the signal feeds a second servomotor (44) which controls the position of the wiper of the second potentiometer. The above time constant is thus controlled by the rate of departure from the glide slope such that gust-like disturbances do not lead to incorrect landing. Specification 987,100 is referred to.

Filed: 1957-06-17
Abstract: 827,247. Preventing explosions in conduits. AEROJET-GENERAL CORPORATION. June 17, 1957, No. 19060/57. Class 47 [Also in Group XXIX] In a conduit carrying explosive fluid, a frangible section of the conduit is arranged to be ruptured by a detonation wave travelling through the fluid, so as to prevent transmission of the detonation beyond the frangible section. In the embodiment of Fig. 1, a frangible conduit section 10 is provided upstream of a looped conduit section 13 which is connected to a downstream conduit section 15, from which a branch conduit 21, reduced in cross-section by a plug 17, extends into contact with the outside of the frangible section 10. The length of the branch section 21 is substantially less than the length of the looped section 13 so that if a detonation wave travels upstream from the section 15, a part of the detonation wave will pass along the branch section 21 to rupture the frangible section 10, before the main part of the detonation wave travelling through the looped section 13 can reach the frangible section. In other embodiments, Figs. 2 and 2a (not shown) the frangible section is surrounded by an annular chamber containing the same fluid as flows in the main conduit, or an explosive liquid having a faster rate of detonation, in which case the annular chamber is closed from the conduit by a thin diaphragm. In another embodiment the branch section is in the form of a small conduit 40, Fig. 3, spiralled around the frangible section 38. The conduit 40 may be filled with the same material as flows in the main conduit, or with a material of faster detonation rate. Only one end of the small bore conduit may be connected to the main conduit, Fig. 3 (not shown).
