Abstract

572,569. Celestial domes. LINK, E. A. April 13, 1939, No. 11448/40. Convention date, Jan. 14, 1939. Divided out of 572,295. [Class 146 (ii)] [Also in Group XXXIII] A celestial dome, for use in training in navigation, has sources of illumination simulating the stars, some or all of which are provided with collimators. In the form shown, an aviator's cockpit 24 mounted as in Specification 370,128 has a transparent dome 27 through which a dome 37 can be observed. The dome has lamps 32 representing the stars, some of the lamps having lens systems 97, Fig. 3, directing parallel beams of light each towards the centre of the dome to enable accurate sextant readings to be taken. The dome 37 is mounted on a carriage 78 so that it can be traversed along a fixed rack 52 and also rotated relative to the carriage to simulate changes of latitude and longitude, and the passage of time, and to enable problems of nagivation normally taking hours to be simulated in a few minutes. These movements are effected from and indicated at an instructor's control panel 65. The dome may be fitted with representations of the stars in both the northern and southern hemispheres alternatively illuminated. Specification 572,295 also is referred to.
