Title: Improvements in prediction apparatus for use in ascertaining the movements of aircraft
IPC: B64D43/00
Filed: 1938-02-14
Abstract: 550,947. Calculating-apparatus. GOLDMAN, B. E. M., and GATTY, O. Feb. 14, 1938, No. 4580. [Class 106. (i)] An apparatus for predicting the movements of aircraft has two or more observation points located according to any desired scale, means for emitting light radiations from said points in accordance with data obtained by observation, and means for detecting the paths of such radiations to ascertain the position, course, speed, angle of climb or descent or other factor affecting the flight. In the application of the invention to the control of aircraft traffic, the apparatus as shown in Figs. 1 and 3 comprises a transparent tank a with points b, c and d on the base representing points on the area to scale over which the aircraft route lies. At each point is arranged a light source movable in elevation and azimuth to correspond with the data obtained at the corresponding points of observation. The intersection of the rays of light planes from the points determines the position of the aircraft. Observing instruments g, h may be provided adjustable for height and azimuth. The light rays emitted may be of various colours. To show the position of the aircraft at any moment a ray d<SP>4</SP>, Fig. 6, representing the course and height is intersected by a ray d<SP>5</SP> at right angles which is movable on a screwed spindle parallel to the course, at the estimated or actual speed. The paths of all aircraft or the progress of a particular aircraft within the area may be observed with the aid of stroboscopic apparatus arranged to set up light planes representing the bearings with suitable frequency as by sending light through slits in a fixed and a rotating coaxial cylinder or by rotating mirror means. If ranges are used as data conical or triangular beams may be employed by employing lenses movable to and from the light sources. Coloured beams may be used for different aircraft. The tank may be filled with smoke, aerosols or other medium to render the rays pr beams visible.

Planes, arrangement of; land-wheels; steering.-In an aeroplane with folding wings and means for driving landwheels from the engine so that the machine may be used as a motor-car, the driving landwheel is arranged between the undercarriage and the tailskid. The wings 1 are hinged to a central plane section or the fuselage so that they can fold backwards, and a driven land-wheel 7 is located between the front wheels 6 and the tail-skid so as to be normally out of contact with the ground, but is brought on to the ground by lowering the fuselage 3 on the undercarriage 15. The undercarriage is arranged to slide on guides 11, Fig. 4, hinged at 12 to the fuselage, and is moved vertically by means of screw gear 9. The wheel 7 may be driven by means of gearing 28 - - 31, Fig. 7, adapted to be coupled to a wheel 27 on the engine shaft by means of a pinion 26. Instead of lowering the fuselage, the wheel 7 alone may be lowered about the axis 30. The front wheels 6 may be steered from the rudder bar 19, Fig. 4, by means of cords 20, 20<x>. Small wheels 4, Fig. 2, may be fitted at the wing-tips. A cable extending from tip to tip in front of the wings may serve to hold them in the extended position. The wings may be stayed to upward extensions of their hinge-pins. Shock of landing, deadening.-The fuselage is slung from the undercarriage by means of rubber cord or steel springs. Propelling.-The propeller shaft is non-rotatably jointed to the engine shaft at 23, Fig. 8, but may be coupled therewith by means of a clutch 24.
