Title: Runway image generating apparatus
IPC: G01S19/40
Filed: 1965-06-14
Abstract: 1,112,552. Aircraft landing aid computer. SPERRY RAND CORPORATION. 14 June, 1965 [12 June, 1964], No. 25067/65. Heading G4G. [Also in Division B7] An aircraft landing aid produces an image of a landing runway on a C.R.T. from signals computed from various flight parameters. Signals from flight instruments 40, 54, 56, 60, 72, 78, 82 representing position and direction of an aircraft carrying the aid, relative to the runway are subjected to multiplication, addition and a cotangent generator 106 to produce A.C. signals. These A.C. signals are either fed directly to the C.R.T., or subjected to halfwave rectification, or passed through either peak detectors 130, 150, 154, 156, 158 or demodulators 59, 88 to produce D.C. signals. The A.C. signals are used to produce lines 1 to 10 on the C.R.T., the D.C. signals to locate these lines. The quantities are derived by analogue computation from the following equations : h (1) R<SP>*</SP> = -, γ 0 is given a constant value so Yo servo 62 responding to altitude, h, will adjust potentiometers 64, 66, 68, 70. These, with assumed constant values for W, L and #L give values to the following equations: By virtue of constant ratios between certain variables potential dividers 94 and 98 can be set to give values to: (5) C N (Y) = #L.γ0/R*-#L α W N (X) of equation (3) (6) W F (X) = W/L+R* αC F (Y) of equation (4) The value of cot # from cotangent generator 106 is fed with values of C<SP>p</SP>(Y) and C N (Y) to multiplying devices 108, 110 to give: (7) C F (X) = C F (Y) cot #. see equation (4) (8) C N (X) = C N (Y) cot #. see equation (5) By means of potential dividers 116, 136 the value of TD(X) of equation (2) is halved. This combined with the effects of inductors 118, 144 and summing devices 122, 126, 146, 138 is used to give values to: from equations (2) (6) (7) from equations (2) (6) (7) from equations (2) (3) (8) from equations (2) (3) (8) The following assumed equalities avoid further computation: (13) S FR (Y) = S FL (Y) = C F (Y) of equation (4) (14) S NL (Y) = S NR (Y) = C N (Y) of equation (5) On the C.R.T. line 1 is TD, line 2 is C F , line 3 is C N , line 4 is W N , line 5 is W F , line 6 is S FL , line 7 is S FR , line 8 is S NL , line 9 is S NR , (X) and (Y) in the above equations indicating the horizontal and vertical components respectively. The lines are fed on to the screen in turn, by logic circuits, e.g. 151, 200, 204, 206, 210 under the control of a digital clock 180.
