St. Male- Meeting to be Repeated. tkA,,t;es in the IN view of th?success attained last year, the authorities in tne neighbourhood of St. Malo have expressed a des.re »^ »«*h£ meeting should be held there, and the >«?MU«fcf °J»S,"el«tinE Automobile Club of France is recommending that another meeting should be organised by the Club for next year. Slack Has a Fall. . with tne STARTING from Villacoublay on Saturday morning with tne intention of making a non-stop flight to Hendon, Robe,ntrf ,„cn(j having got off his course while among the clouds, tned to jaw between Ostend and Blankenberghe. The machine in landing, however, capsized and was slightly damaged. Testing a Variable Speed Machine. . AT Miramas, a young aviator, by name Jourjon, is testing a machine invented by M. Bernard de Beer, which is so arranged that the speed of the machine can be varied. Testing the Borel Arroyacht. , < >.N Sunday and Monday Divetain, on the Borel aeroyacnt, which he had flown over from La Rochelle, made a series of flights at Les Sables d'Olonne. With a passenger and enough fuel tor four hours' Hying on board, he made one trip of half an hour s dura tion at a height of 1,200 metres. 470 kilom. Flight by Hirth. HUTS, on an Albatross monoplane with Benz motor, started from Johannisthal on the 25th ult., and flew to Mannheim, the distance of 470 kiloms. being traversed in five hours, while the average altitude was 2,000 metres. The machine carried a passenger. Hirth intended going on to Paris. A Sign of the Times. INFORMATION is to hand from Germany to the effect that the authorities at the flying ground at Gotha have decided, in view of the amount of betting which goes on in connection with the flying races, to introduce " totalisator" machines as used at the horse race meetings. From Berlin to Posen. ALSO on the 25th ult., Laitach on his aeroplane took Capt. Haehrtc! from Berlin to Posen, a distance of about 230 kilos, ill 3 hrg. 3 rains. Volunteer Airmen for German Navy. IN order to expedite the organisation of the Naval aeroplane service, the German Naval Authorities have decided to accept this year volunteers, who must have a Pilot's Certificate, for one year's service. Cross-country Flying in Germany. IN connection with a meeting at Dresden on the 23rd ult., Lieut. Echenbrecher, on an Erzgeberge monoplane, flew from Dresden to Bantzen and back in 55 mins. i A German Fatality. WHILE testing a new monoplane at Johannisthal on the 22nd nit., Wheelmer fell from a height of 100 metres and was killed on the spot. A Hanriot for Italian Army. ON the 23rd ult. Bielovucic was testing at the Mirafiori aero drome, the Hanriot monoplane given to the Italian Army by Baron Leonino de Zara. On Saturday, on this machine he made a flight from Mirafiori to l'inerolo and back. The Aerial Destroyer. f _J Fl5°r- NoiPles» Ar«ona, comes the information that the Mexican federal Gunboat "Tampico," lying in Guaymas Harbour, was destroyed by a bomb dropped from an aeroplane piloted by Didier Masson. The gunboat, it is stated, was blown up at the fourth attempt. A Russian Height Record. ON a Sikorsky biplane, on the 22nd ult., at the St. Petersburg Military Aerodrome, Lieut. Aleelchnovitch beat Gaber-Vlinsky's ofTrTn, >& rr£rd b>'S0'n8 UP t0 3'4°° metres> an improvement «rflHn , c mi'ns '*"* "" "^ *" *4 "^ 3nd the retUrn to Fast Flying in Russia. ON a Sikorsky monocoque aeroplane, Jankowsky, the other day flew from St Petersburg to Gatchina and back at a speed which was stated to be 159 kiloms. an hour. Russian Officer Killed. WHILE making a vol plant in calm weather at the Gatchina mihtary aerodrome, on Tuesday, the biplane of Capi. TaE capped when at a height of 200 metre,. The pilot died iroTrns injuries very shortly afterwards. AUGUST 2, 1913. SC.ENTIP.C .NSTRU^N^THE^DESlGK AND Yaw-meter. Th, folio wine is unotner instrument described by Mr. Darwin in The following is -DULI recentlV under the above heading :— "Vhrw^d Sis hereUufed Intense of << to bend or deviate The word i aw is "e accurately describe ., s, , . 1 _ _po.iv it is moving in the direction 01 us icugui. t-A tt ihTs melured by". If we consider the aeroplane at fesfand'the a"r blow ng against it, it measures how nearly the direc- rest and me air D j s m ^ meets the eroplne' ZdirSn of the wind will change and this will be indicated A wind-vane carried by an airship or aeroplane would also show how nearly the movement was head on in the same way as the Yaw-meter. But the wind-vane would be difficult to read when p aJdTn a position free from eddies in the air caused by the Tifcraft itself! With the Yaw-meter the dial and hand can be Dlaced in a convenient place for observation. P Two Pilot tubes are made like the letterY (see Fig 5, p- 600) with the openings at the tops of the two arms If the wind blows symme trically to The two tubes the pressure will be equal in both. But if he direction of the wind changes it will meet the opening at the end of one tube more nearly in the direction 111 which the tube is pointing, and the pressure will be increased. The opposite will take place in the other Pitot tube and the pressure in it will be diminished. The pressure from these two Pitot tubes is taken by two pipes to the indicating apparatus, which can be at any convenient distance away. Each tube is connected to a circular box, the top of which is an air-tight flexible diaphragm which can move outwards. A rod is connected to each diaphragm, and these rods are pushed outwards by the air pressure. . The hand indicating the angle of Yaw, that is the angle at which the air meets the Y Pitot tube, is pivoted about the point 0, and is continued to P. At this point it is connected to the two rods from the diaphragms by a freely moving joint. If one rod pushes with a. greater force than the other the hand is moved over to one side, and it will come to rest when OP is in the direction of the resultant of the forces with which the two rods are pushed outwards, and when it is in equilibrium the hand will show on the scale the angle of Yaw, If the speed of the aeroplane increases the hand will not move, because the air pressure and consequently the pushing forces in the two rods will both be increased in the same ratio. The same instrument can be connected to a wind-vane which moves the Y Pitot tubes so as to face the wind. The tubes are arranged to show if the wind has an upward or downward tendency, and the angle between the direction of the wind and a horizontal plane is measured. ® ® ® ® Filling a Want at Amesbury. THE Salisbury Plain Motors, Ltd., write us as follows: "It may be of interest to pupils and aviators in the Salisbury Plain district to know that a new garage has been opened in Amesbury, under the title of Salisbury Plain Motors, Ltd. The directors are Capt. Clutton, who was the original secretary and builder of the Hendon aerodrome, and Mr. Bouwens, who was one of the first pupils to secure his brevet there at the B16riot school. ^^m^l^wm \\ s* in i| , ,tffajmmmB*& **& sf||f! £ Ml ' " ... " 85S The premises include a workshop fitted with modern machinery, and capable of dealing with all repairs except those of the very largest description, also a large garage with 7 lock-ups, and a very complete stock of engineers' stores as well as the usual petrols, oils and greases. A stock of Continental, Avon, and Spencer-Moulton tyres are kept, and electric light is installed throughout. The premises are seen in the above photograph. A new departure is the policy of hiring motor cycles and small cars without as well as with drivers for long or short periods—a great convenience to those who are quartered at inaccessible points of this very inaccessible neighbourhood."
