action is thus devoid of shocks, and any movement of the by-passes is gradual and lacking in jerkiness that would tend to produce undesirable shocks to the mechanism as a whole. In other wonjs, the control system has been arranged to have a more or less damping action, making any changes in the amount of gases passing to the turbine gradual rather than sudden enough to cause trouble. In operation of the, supercharges the air is drawn in through the passage, G, is carried around by the impeller, A, and in its compressed state is sent to the carburettors through the outlet, J. The exhaust gases are led to the gas-chamber, N, whence they are directed through the nozzles, R, to the buckets, K, of the turbine wheel, B. The exhaust gases, after giving up their energy, are discharged through the exhaust outlet, E, into which the valves, V, also send any gases which are not sent through the turbine, due to the automatic control already mentioned. There is in reality no connection between the turbine and the compressor, except through the common shaft, S, which is fitted with a • 3> An Irish Aerial Derby IN connection with the Royal Air Force sports at Lans- downe Road, Dublin, an aerial Derby was held on August 8 over a course from Tallaght, Co. Dublin, to the Curragh, then to Gormanstown, Co. Meath ; from there to Dublin, and from Dublin to Tallaght, a distance of 102J miles. The machines were handicapped on the Air Ministry's ratings of speed. Twenty-one machines took part, including Maj. C. J. Mackey, M.C., D.F.C. (R.E. 8), Lieut. T. H. Langrishe (Clerget Avro), Lieut. F. A. Urmiston (Mono Avro), Capt. F. Workman, M.C. (Clerget Avro), Lieut. W. A. Roberts (Clerget Avro), Lieut. W. E. Davies (Clerget Avro), Capt. F. C. Mailer, A.F.C. (D.H. 9), Lieut. J. S. Chick, M.C. (D.H. 9), Capt. M'Keon (S.E. 5), Capt. R. B. Bourne (D.H. 9), Lieut. Rodwill, R.I. (D. H. 9), Capt. Bowen (D.H. 9), Lieut. T. H. Wright (Clerget Avro), Capt. Seagrave (Mono Avro), Lieut. P. D. Baker (Mono Avro), Major Baker (Bristol), Lieut. Woodman (Bristol), Lieut. Holland (Bristol), Captain Sibley (Mono Avro), Capt. Gerard (Camel), Lieut. Mansfield (Bristol). The result was asjollows :—Lieut. Urmiston, 1 h. 9 m. 34 s.; Capt. Sibley, 1 h. 9 m. 35 s. ; and Lieut. Baker, 1 h. n m. 55 s. Capt. Sibley was disqualified for finishing on the wrong side of the post, and the second place was given to Lieut. Baker, while Lieut. Roberts was given third place, 1 h. n m. 55 s. The Hotel Cecil WITH the exception of the wireless operators, who will remain until the masts have been taken down, the Air Ministry vacated the Hotel Cecil on Tuesday. It is estimated that it will take six months to restore the building to the condition in which it was when taken over. Flying Boat's Return THE British flying boat F. 5, which left Felixstowe on July 19 on a test flight over Scandinavia, returned to England rm August 6 She left Eabjerg, Denmark, at noon and reached Felixstowe at 7.15 a.m. The distance is 300 miles but the machine had to contend with a head wind all the way. A Flying Week for Nottingham ON Friday Maj. McMinnies flew from Southport to Notting ham to see Sir Jesse Boot, landing in a small field next to Boots's recreation ground. He transacted his business and was back in Southport again in the time that it would have taken to reach Nottingham by train. It is probable that a flying week and aerial gymkana and f§te will take place at Nottingham during September. A New Passenger Height Record Claim AT Villacoublay on August 8 Maurice Walbaum, accom panied by his mechanic, Tisse, on a Breguet 300 h.p. Renault, set out to beat the world's passenger height record. In his first attemptat 5.30 p.m. he got up to 6,000 metres in 27 mins., and then landed at Issy. An hour later he went up again, and Tbis time got to 7,800 metres (25,740 ft.). He landed at Villacoublay at 7 p.m. The official world's height record for pilot and one passenger stands to the credit of Bier, the Austrian pilot, at 6,170 metres, but Capt. Lang and Lieut. Blowes, on a Napier-engined De H.9. in January last went up to a height, officially certified to be 28,000 ft. Flying Through the Arc de Triomphe IN defiance of an official interdict a Frenchman, Charles Godefroi, has succeeded in flying through the Arc de Triomphe, the feat which even the French have been moved to term tine prouesse folk, and in practising for which Navarre lost his AUGUST 14, 1919' labyrinth between the two rotors to prevent pressure escape from the turbine to the blower casting. As a means of cooling, water is circulated through the space, W, between the two parts, a provision which was quite essential to assist in keep ing down the excessive temperature. The Sherbondy machine was designed to have an air discharge capacity of 692 cub. ft. per minute when the Liberty engine is operating at 1,700 r.p.m. Under these conditions, it. is intended to handle any pressure requirements of the engine from nothing at sea level to approximately 7.5 lbs. per sq. in. at 20,000 ft., at which altitude the atmospheric pressure is about half that at sea level. It is computed that the theoretical horse-power available in the exhaust gas of the Liberty engine is about 80, whereas, with a compressor efficiency of around 60 per cent, the horse power required to compress the air is about 32, indicating that the overall efficiency of the system is somewhere in the neighbourhood of 40 per cent. (To be concluded.) life. The flight was made soon after 7 a.m., on a Nieuport, of 9 metres span, fitted with a 120 h.p. Le Rhone motor. The height of the opening in the Arc de Triomphe is 29.42 metres and the width between the pillars 14.62 metres. Godefroi flew up the Avenue de la Grand Armee through the Arch to the Concorde where he managed to get above the trees and turned back to Villacoublay. The authorities have been much perturbed by the flight and have prohibited the exhibition of a film showing it. They also endeavoured to suppress all illustrations but found this impossible. The Army authorities, it is under stood, are holding an inquiry to discover how Godefroi, who was a sergeant in the Air Service until his demobilisation last week, secured possession of a military machine. • A Motorless Flyer DURING the War the competition for the Peugeot prize of ^400 for a flight of 10 metres carried out with no other motive power than that furnished by the pilot, has been in abeyance. Recently, however, interest in it has revived, and there has been a lot of strenuous practising lately. A message from Paris on August 11 announced that the well-known French cyclist, Poulain, at Longchamps, had made a hop of 12 metres at a height of 1 metre, his speed being 9 km. per hour. Smuggling Saxon Crown Jewels IT is reported from Malmo that an attempt was made on August 9 to bring valuables belonging to the ex-King of Saxony into Sweden, states the Times correspondent at Copenhagen. At 9 a.m. a seaplane approached the coast at Smygehuk, the southernmost point of Sweden, and a German couple, who for some time had been living in the neighbourhood, had come down to the shore. After an exchange of signals the airman dropped two parcels, and then returned. The coastguard, seeing the incident, and thinking that smuggling was being attempted, tried to catch the Germans, who, however, succeeded in escaping. Meanwhile the Stock holm police had been informed by telephone, and later in the day the Germans were arrested at the neighbouring railway station. They first maintained that the parcels had fallen into the sea, but these were duly found when the Germans were searched. The parcels contained some exquisite lace, jewellery and Government securities amounting to large sums, belonging to the ex-King of Saxony. The valuables have been retained by the authorities. According to a later message, the woman is a countess and the man a Dresden court official. Aeroplane Disaster in Germany ACCORDING to messages from Berlin a giant flying machine hired by the Ukrainian Government was shot down by Polish troops in the Forest of Routen, and the 10 people on board, including M. Vitovsky, formerly the West Ukrainian Minister of War, were killed. The pilot was Bendercich, and the machine carried a crew of five, as well as four passengers. Trie machine was on its way from Breslau to the Ukraine when the catastrophe occurred. Besides the dead bodies there were found scattered about round the spot where the machine fell several bags and quantities of Russian gold coin and currency notes. To Fly to Spitsbergen A BRITISH aviator is at present at Bergen with his machine, and is about to leave by steamship for Tromso, whence he will fly to Spitzbergen, according to a message from The Times correspondent at Christiania.
