DECEMBER 13, 1913 [fljGMI Looping the Loop at Nice. ON several days last week Hanouille gave numerous displays of looping the loop, &c, on his Bleriot machine at Nice, while on Sunday afternoon during a flight of half an hour over the Anges Bay he gave a special exhibition of turning on one wing and S dives and looped the loop ten times, these evolutions being watched by a large crowd on the Promenade des Anglais and the jetty. Chevillard at Lille. LAST Sunday afternoon about 20,000 people gathered at the Ronehin aerodrome at Lille, to see a fine exhibition of upside-down flying and looping the loop carried out by Chevillard on his Henry Farman machine. Pegoud Back at Buc. LAST week Pegoud was back at Buc, and on the 4th inst. made some exhibition flights, including turning with the planes vertical, dives on the wings, and tail dives, upside-down flying, Z dives, and a series of loops. On Sunday afternoon he was flying a two-seater Bleriot, but made no attempt at upside-down flying. Bidot was, however, carrying out some tests with a parachute from a Bleriot machine. Testing the Edelweiss Motor. ON Sunday, at Villacoublay, Espanet made several fine flights on a Nieuport fitted with a new radial motor, the Edelweiss, one of the new comers on view at the Paris Show. For Night Arrivals at Buc. FOR the guidance of aviators who arrive at Buc after dusk, special lights have been installed at the Bleriot and Farman aerodromes, and they are now working. Bidot Succeeds Perreyon. BlDOT, who has made a number of fine flights on the Bleriot monoplane, has now been appointed in the place of the late M. Perreyon as chef pilote at the Bleriot school at Buc. French Navy Has Another Voisin Canard. AT Frejus, on Monday of last week, Rugere carried out the official tests with a new Voisin Canard which has just been delivered to the French Navy. Piloted by Mechanic Parfait, it made an hour's flight with a passenger at an average height of 800 metres, and was steered over the town. Quick Climbing on a Ponnler. TESTING one of the new Ponnier monoplanes at Rheims on Monday, Bielovucic climbed at the rate of 350 metres a minute with a normal load, which is claimed as being a record. The machine is fitted with a 60 h. p. Rhone motor and Chauviere propeller. November at Johannisthal. DURING last month flying was possible at Johannisthal on 28 days, and 132 pilots made 4,325 flights aggregating 450 hrs. 33 mins. Seventeen civilian pupils obtained certificates and 16 military pupils qualified. Cbanteloup in Holland. QUEEN WILHEI.MINA having expressed a wish to see some upside-down flying, Chanteloup gave a special display on his Caudron biplane on Sunday afternoon at the Hague. 1 le flew in a circle with the planes vertical, made an S dive, and then a double loop, followed by a triple loop. About 30,000 people were present on the flying ground. He gave similar demonstrations on the 3'd and 4th inst. at Groningen. The Progress of Vedrines. LEAVING Belgrade on the 3rd inst., Vedrines flew on his Bleriot to Sofia, where, on the following day, he was received by King Ferdinand. He left Sofia on the 5th inst. for Constantinople. Bonnier at Constantinople. LEAVING Bucharest on the 2nd inst., Bonnier, on his Nieuport monoplane, arrived at Varna, from which point he flew on lo Constantinople on the following day. The Prince Henry Circuit. IT has now been decided that the Prince Henry Circuit shall be held from May 17 to 25. On the first day a circuit will lie made from Darmstadt, via Mannheim, Strasburg, Spire and Worms, and on the second day the competitors will go from Darmstadt to Frankfort by way of Mayence, Coblentz, and Cologne ; the third stage will be by Cassel, Munster, and Hanover to Hamburg ; the fourth to Cologne and back, and the last to Cologne where the military scouting tests will be held. There will 1* a day's rest between each stage. St. Petersburg to Moscow and Back. AN unsuccessful attempt was made by Wassilieff at the end of last month to win the Romanoff Cup, which calls for a flight from St. Petersburg to Moscow and back within 48 hours. Leaving St. Petersburg on his Morane-Saulnier monoplane on November 24th, at 9.44 a.m., Wassilieff flew 360 kiloms. to Bychny-Voletchek, and then had to stop until the next morning on account of the heavy snowstorms. The next day at 7.32 a.m. he restarted, and flew in 2 hrs. 20 mins. to Moscow, where he did not stop, but dropped a certificate as to his time of departure trom St. Petersburg. He landed at Tver later, at 11.36, having covered about 450 kiloms. in a little over four hours. After replenishing fuel tanks, etc., he got away at 1.20, but after flying 190 kiloms. was in trouble with a frozen car burettor. Unfortunately he had to come down on very bad ground near Alechenka, and damaged the chassis. A new wheel arrived, and was fitted, but subsequent tyre trouble prevented further pro gress that day. Next morning the journey was resumed at 10.25 a.m., and at 12.53 P-m- lne machine landed at St. Petersburg, but unfortunately the time taken for the full distance of 1,280kiloms. exceeded the maximum time allowed. Russian Aviator Drowned. AFTER a long flight on a hydro-aeroplane, the Russian Lieut. Wachsmuth fell into the sea at Leban, and was drowned, on the 7th inst. ® ® ® ® PROPORTIONATE LOAD CARRIED BY THE WING SPARS. IN order to estimate the relative load carried by the front and rear spars of a wing it is necessary to test the wing (in model form) to obtain a graph of the travel of the c.p. The c.p. curve for the much used BloriotXI. bis section is known, and is given in the diagram. Superimposed on the same diagram is a section of the wing showing the position of the spars. It is then necessary to determine the range of flight speeds of which the machine is capable, and to express those limit* m terms of the angles of incidence assumed by the wing. For instance, suppose the low speed limit is flown at 10" incidence, and the fast speed limit at J° incidence. When flying fast the c.p. is half way along the chord ; when flying flow it is '28 of the chord from the leading edge. The positions of the spars are indicated in the diagram, and the loads carried by each are as follows : — Load on front spar at 10°. Distance l>etween spars = '47 Distance of c.p. from rear spar = ('675 ~ '2%) = "395 •e 7 8 •» " Flight'' Copyright. Diagram illustrating the travel of the centre of pressure on the wing section, B16rlot XI 018. 1 A t . '3°5 .'. load on front spar = - Load on rear spar at J°. Distance between spars = '47 Distance of c.p. from front spar = ("5 - •295 •47 load on rear spar = 84 per cent. 205) 63 per cent. 1363
