"5°° FLIGHT MAY 29TH, 1947 THE CONCORDIA spar, which is a pressed channel carrying additional L- section reinforcing booms ; the spanwise stringers are bulb- angle members for which the ribs are notched. Each elevator is built up with a single pressed channel nose spar, forward of, which the leading edge is fashioned as a torsion box. Chordal ribs are simple pressed-sheet units, and these are supplemented by intercostal bulb-angle stringers. Each elevator has a forward-raking horn balance at the tip and is swung on three self-aligning ball-bearing hinges which are carried off the tailplane rear spar. The inboard ends of each elevator are cut-away in order to permit rudder movement, the aerofoil section of the eleva- tor at this station necessarily having an abruptly rounded trailing edge. On each elevator is a metal tab, that on the post surface being a trim tab, and that on the starboard surface a conventional-type geared servo tab. The fin is built up on two spars, or posts, the forward member raking aft and the rearward member raking for- ward. Both fin posts are pressed channels with boom rein- forcement, and the chordal ribs are pressed sheet dia- phragms stabilized with L-section strips; the attachment fittings to the fuselage are conventional fork and lug units as already described. Structurally the rudder is essentially similar to ailerons and elevators, and it is swung on three self-aligning ball- bearing hinges. A split tab is embodied in the trailing edge, the lower portion being a trim surface, whilst the upper por- tion is a geared servo. Approximately 8in below the tab the rear navigation light is embodied in the trailing edge. Rudder actuation is accomplished by a push-pull rod emerg- ing from the side of the fuselage just forward of the rudder, this being pivoted to a horn lever carried to starboard off the rudder spar T.K.S. de-icing strips are incorporated in the leading edges of the outer wings, tailplane and fin. o-*~V" lt.Ac.S. MEDALS AND PHIZES IT has been announced thatthe following awards have been made by theCouncil of the Royal Aero- nautical Society: TheSimms Gold Medal, for the best Paper read before theSociety in any year on any science related to aero-nautics, goes to Professor L. Aitchison, Professor of In-dustrial iMetallurgy at Birmingham University for his Paper "Aeronautics and the Metallurgist." Professor A. R. Collar, Sir George White Professor of Aero-nautical Engineering, Bristol University, gets the George Tay- lor (of Australia) Gold Medal awarded annually at the discretionof the Council for the most valuable Paper submitted of read during the previous season. Professor Collar's contribution was" Aeroelastic Problems at High Speed." Mr. Edwin Link, designer of the Link Trainer, was awardedthe Wakefield Gold Medal which is presented annually to the designer of any invention or apparatus tending towards safetyin flying. The Society's Silver Medal awarded at the discretion of the Council for some advance in aeronautical design goes toMr. VV. G. Carter, Chief Designer of the Gloster Aircraft Co., for his work on the development and design of jet-propelledaircraft. Mr. J. K. Harvey, Royal Aircraft Establishment, has wonthe R38 Memorial Prize offered each year for the best Paper received by the Society on some subject of a technical naturein the science of aeronautics, preference being given to Papers which relate to airships. The subject chosen by Mr. Hardvwas "Protection of Aircraft Against Ice." Finally, the Edward Busk Memorial Prize for the best Paper Details of sgair attachments and joints. , Th";"^-'1 irkpfelation to the main cut-awa^1 Mr. Edwin Link Mr. J. Smith C.B.E. Mr. W. G. Carter, M.B.E. Prof. Leslie Aitchison received by the Society on seme subject of a technical naturein connection with aircraft, including seaplanes, this year goes to Mr. J. Smith, Chief Designer, Vickers-Armstrongs, Ltd.,Supermarine Works, for his " Development of the Spitfire and Seafire " Paper. A HAWKER RESIGNATION A FTER sixteen years with the firm, Mr. Philip Lucas has**• resigned from his position as director and general manager of Hawker Aircraft, Ltd. We gather it is a question of adifference of opinion on policy. Mr. Lucas joined the company as test pilot in 1931, and did much demonstration and deliverywork during the Hart and Fury period. The later Hawker types were his responsibility, and it was while testing the proto-type Typhoon that the fuselage began to break, but Lucas stuck to the machine and landed it safely, a cool piece ofcourage which saved long delays in production, and for which he was awarded the George Medal. AUSTER DISTRIBUTORS T OXHAM'S have been appointed Auster distributors for the-L* whole of the North East of England. They are already handling the distribution of Auster aircraft in the N.W. area.
