Ringway Expansion •>Mf • .-v""''.. THE Ministry of Civil Aviation hasapproved a scheme for the extensionof the existing main runway at Ringway Airport, Manchester, to a length of5,900ft, and for enlargement of the apron.

News from Australia '"THE first of two prototype Common-J- wealth CA-22 trainers being built for the R.A.A.F. is expected to fly withinthe next six months, according to a report from Australia. Production air-craft, it is said, may be powered by a 450 h.p. engine of Australian design in-stead of the Pratt and Whitney Wasp Junior at present specified. This unit isto be named the Cicada; its manufac- turers have not yet been announced. Production of ' Vampires for theR.A.A.F. is reported to have been held up by the seven-week Australian coal-strike ; the second machine was delivered in December. By mid-rq.50, productionis expected to reach two aircraft per month, and later to a rate ensuring de-livery of the complete batch of 50 by the second half of next year. Most Powerful Turbojet? A STATIC-THRUST rating of 9,200 lbis quoted for the Allison J-35-23 turbojet, which will be the power unit offuture models of Boeing B-47 Stratojet bombers for the U.S.A.F. The firstB-47S (suffixed A and B) are powered by six General Electric J-47 axial units(each of 5,000 lb static thrust) and have a maximum speed of over 600 m.p.h.The prototype had earlier J-35 turbojets, with a maximum rating of only 3,750 lb.The enormous increase in power avail- able to the B-47 will certainly give ahigher performance, although, in level flight, the airframe may not be able totake full advantage of over 55,000 lb thrust. SLOWING DOWN QUICKLY: The Northrop rocket-propelled sleigh with which the U.S.A.F. is conducting tests to determine human resistance to high decelerative forces. The volunteer is preparing for high-speed (175-240 m.p.h.) travel along the 2,000ft test-track, which terminates in a 45ft braking section. • . . •;«:.- The Brabazon in Detail equipment of the great Bristol aircraft A and its power plants, and contains largeSMALL supply of reprints of The fold-out two-colour drawings of the Story of the Brabazon is still avail- interior layout - - - - -able.
