Abstract
564,747. Preventing formation of snow &c. on aircraft. FLIGHT REFUELLING, Ltd., LANGLEY, M., SMITH, C. H., and GERRITSEN, J. J. Feb. 19, 1943, No. 2831. [Class 4] Apparatus for delivering de-icing liquid to surfaces of aircraft &c. comprises flow resisting passages in the form of gaps between rigid members with opposed parallel surfaces, the length of the passages in the direction of flow being great as compared with the distance between the surfaces and the liquid being forced under pressure through the passages. According to Fig. 1, the limbs 3 of a V-section member arranged at the leading edge of an aircraft wing 1 are closely spaced apart by shims 6 to provide flow resistance gaps 7 and are clamped together by bolts 5, de-icing liquid being supplied under pressure by a pipe 9. The gaps may be formed by slots in the surface of the members 3 instead of by shims. In Fig. 2, the resistance gap is formed between members 11 between which is clamped a strip 13 of flexible permeable material folded into a pad 17 and secured to the surface 16 to which the liquid is to be distributed. The liquid is' supplied to the space 14 by pipe 15. Fig. 4 shows a balloon-barrage cutter provided with a knife-cutter 23, nose-forming strips 22 and a covering 21 of permeable material. De-icing liquid supplied to ducts 24 is discharged through flow resistance gaps formed between sheets 25, 26, to the space between the surface 20 and the covering 21 which serves to spread the liquid. The permeable material may be moulded resin, leather, fabric, gauze, &c. The liquid may be supplied under gravity or gas pressure from a reservoir which may be multi-cellular with a cell for each section of the de-icing system, or it may be supplied by a meter delivering under pressure. The supply may be rendered intermittent in the manner of a self-siphoning tank or when a meter is used, by the intermittent operation thereof or by the meter storing up a charge of liquid under pressure, the charge being released by a valve geared to the meter. Specification 473,883 is referred to.
