JANUARY grn, 1941. '//,„/'/>l-X, y/,y //„- f 'f /'fm/'r/f// r///f/ '/////, HERE AND Civil Aviation in PortugalT HAT the war h^s'not affected to anygreat extent-civil air activities in Portugal (which even in peacetime arenever very great) is revealed by the fact that this month subsidies are to be paidto i5 civjl pilots who got their licences at thtjir own expense. The grant isabout £30 each. Small German Airliner T~\ESPITE the war Germany is not en-*-* tirely stopping her civil air develop- ment, for the Siebel Flugzeugwerke hasproduced a twin-engined low wing mono- plane to carry eight passengers and acrew of two. This is powered with two Argus AS410 vee type engines of360 h.p. Construction is of all-metal stressed-skin. Maximum speed is be-lieved to be about 200 m.p.h. at 10,000ft. and maximum range 1,240miles. Aircraft Production TTMIE January issue of Aircraft Produc-•»• tion just published contains the first instalment of an article dealing with theproduction of the "shadow" Blenheim bomber. It is profusely illustrated.Other articles deal with the welding of airframes, the manufacture of rivets fromlight-alloy sheet, the production of high- strength alloy castings, and a discussionof the future use of magnesium alloys in airframe construction. A range ofmachine tools and small tools for efficient production is also reviewed. German Aircraft IdentificationR EADERS are reminded that an en-tirely new identification chart of Herman aircraft, suitable for hanging,has been prepared by Flight. The new chart (a reproduction on a reduced scalewas published in our issue of December 19, 1940), which is printed on a cardmeasuring 22in. x I4|in., includes one COMPLIMENTS. Forhis Christmas card this year the Secretaryof State for Air chose this Flight photographof a Long - nosed Blenheim. or two new typesof aircraft, and in- corporates improve-ments introduced as a result of the use ofmany thousands of earlier editions ofthe chart all over the country andthroughout the ser- vices. The price isone shilling, plus sixpence for postagefor single copies. Postage on two ormore copies up to six is eightpience,and for twelve copies is ejjfcvenpencit j : Another Canaaian Factoty A NEW factory will he established in•** Western Ontario for the production of newest types ojffast fighters, it hasbeen announced jpy Mr. C. D. Howe, Minister for Munitions and Supply inCanada. The AJinister said it would be the first factory/in Canada in which air- I craft ,co\|ld bejBuilt on an assembly line. \ Mr. Howd adjied that as yet there had-b,ee» no decision on the exact type b| fighter to be produced. /' f*" i Resinoid Adhesive—--"' THE U.S. Plywood Corporation hasintroduced a synthetic resinoid adhesive known as "Weldwood," forwhich great strength as a cement for wood is claimed. One of the ureaformaldehydes, it is in the form of a powder which dissolves in cold water.It hardens in four hours to give a water- tight bond which so far has always beenfound to be stronger than the mahogany on which it has been tested. Portuguese PrecautionsT HE Government of Portugal hasissued an order forbidding foreigners to attend Portuguese flying schools andip fly over Portuguesr territory. The new order does not affect authorisedcommercial air services, which are ex- cluded from the prohibition. "Boom" at the B.B.C. OX January .5 Marshal of the RoyalAir Force, Lord Trenchard, broke his intention never to broadcast. It wasfitting that the one object for the benefit of which he broke his resolution was theR.A.F. Benevolent Fund, started by hiin after the war 1914-18. Flight is sin-cerely glad that Lord Trenchard did make his appeal. The R.A.F. Benevo-lent Fund is just about the most worthy cause which could have been chosen, and THERE it is to be hoped that the Fund will bene-fit handsomely. Contributions should be sent to Lord Trenchard, R.A.F. Bene-volent Fund, 14, Eaton Grove, Hove, Sussex. Clippers for B.O.A.F ROM America it is reported thatthree Boeing Clippers have been pur- chased from Pan-American Airways foruse on the British Empire routes. A British crew is now in America tofamiliarise itself with the handling of tho type. Delivery is expected shortly. Admiral for M.A.P. ADMIRAL SIR NOEL LAURENCE'•**• has been appointed assistant to the i|/ Minister for Aircraft Production. Sir ?Noel had a distinguished career in the war 1914-18, mainly in submarine work,and in 1936 he became Vice-Admiral Commanding aircraft carriers, so that hehas intimate first-hand knowledge and experience of carriers and of the FleetAir Arm generally. The Parker "Family" Grows '"PHERE was a time, it seems almost-*- unbelievable now, when Mr. Lankes- ter Parker had so few Short flying boatsto test that he had to fly the little "Mussel " in order to keep his hands in.Long ago, when orders for Empire boats and other craft began to materialise, hegot Mr. H. L. Piper to lend a hand. Even the two had more than they couldhandle if deliveries were not to be held up, and Sqn. Ldr. E. J. Moreton joinedthe team. A fourth test pilot became necessary presently, and Mr. G. A. V.Tyson, who was familiar with Short air- craft from his experimental work whilehe was with Flight Refuelling, Ltd., was chosen. Their accumulated experienceshould be invaluable to Short Brothers. Silence, Please! , /~*ERMAN claims to have evolved an-.VJ effective silencer for aircraft engines v need cause no undue alarm. There is nogreat difficulty in silencing the exhaust, although usually a certain loss of poweris likely to result. There are, of course, other noises which cannot be silenced,such as that of the airscrew. It is worth noting, however, thatcoupled with the announcement of the silent engine is the report of an " in-visible " aeroplane, the covering material of which is said to be mica. Exactlywhy mica should have been chosen is not clear, since there are many syntheticresins which could be used. Most likely the whole story is an attempt at dis-guising the fact that Germany is pre- paring new types of aircraft capable offlying at such great altitudes that they cannot be seen from the ground, andneither can the engines be heard. In any case, there are so many structuralparts in an aircraft which cannot be made of transparent material, and somuch equipment, that to cover the re- mainder with transparent material wouldnot great] - reduce visibility.
