MARCH 14. T935- FLIGHT. l6q One half of the crank case, with crankshafts and airscrew shaft. The main bearings are of the plain lead-bronze type. ^returned to the tank by two gear-type scavenge pumps. It might be expected that cooling of an engine of this ayout would present difficulties. Actually, to quote an example, the '' Rapier IV '' has been found to cool fquite satisfactorily in a flying boat with a top speed of about 120 m.p.h. Baffles direct the cooling draught round the backs of the cylinders. Cooling air from a chute is "ollected between adjacent blocks of cylinders and escapes through the fins to the outsides of the banks, whence it is led away through a suitable slot in the cowling. A logical development of the "Rapier," once the "H" arrangement of the cylinders had been proved, was a 24- cylinder engine of generally similar design. Such an engine has now been produced, and is known as the Napier " Dagger," of 760 h.p. A batch of these has recently been ordered for the equipment of a R.A.F. squadron. KING'S CUP REGULATIONS A " Go As You Please " Eliminating Test : New Territory to be Covered tGLLATIONS for this year's King's Cup Race, which lakes place on Friday and Saturdav, September 6 and 7, starting and finishing at Hatfield, have now been issued . by the Royal Aero Club. The selection of this compara- w-iv late date in the year is partlv to avoid clashing with oe jubilee celebrations and partly because, in the late summer, earner conditions are usually most favourable over the unneriv and most difficult section of the eliminating course. f the vii °fithlS year's race is to provide a combined test ue:SEUI and navigating qualities of the competing pilots w 0 the speed and reliability of the aircraft, while at the i Possible enSUnDg that the final Sha11 be as rePr««itative f ^eliminating contest on the first day will be in the nature at theJf J°t E ease tria1'" the only requirements being °>rol\S* Slrlall,land and eheck in at each of the official ftheoE%°f WhlCh there wil1 be four' and turn at each For th mng Points. «hmesewinU^0Sr -°,f ,th.e eliminating contest competing w *m be divided into two classes: — exceed ^n K h t0t&l engine powcr of which does not tionsperminiifefU maximum permissible revolu- per nnnute of the engine(s); For the Taft exceeding this power. u m permissibleTr, ™ ^ classification the power at maxi-e engine tvn, i ,, tne ^Pe engine, as established in The course! \K' wJ1 be taken- territory wilhi„* tl,rn">ating contest will cover a good deal any King's Cm T?

Late entries at double fees will be received up to 5 p.m. on July 30. The Late John Tranum It is with regret that Flight records the passing of John Tranum, the famous parachutist, who died when he was about to embark on a 30,000 ft. parachute jump last Thursday. He was a passenger in a Danish military machine flown by Capt. Laerum, and intended to break the world's record for a delayed drop. When the machine reached a height of 27,000 ft. he collapsed, after signalling to the pilot that something was wrong. Capt. Laerum dived for Kastrup aerodrome but on landing it was found that Tranum was unconscious, and all efforts to revive him failed. At the official enquiry into the tragedy it was concluded that death was due to heart failure resulting from nerve strain. Tranum, a Dane by birth, performed some of the more spectacular of his " stunts " in America, but in England he is, perhaps, best known for his delayed drop of 17,250 ft,, made at Netheravon in May, 1933.
