MAY 9, 1914. (/ycHT] THE SANCHEZ-BESA BIPLANE. THE subject of our scale drawings this week, the Sanchez - Besa biplane, which paid a brief visit to Hendon aerodrome during last week-end, is similar in its general arrangement to the machine exhibited at the last Paris Aero Show, when it was fully described in these columns. The chief alteration appears to be that this machine is fitted with an 80 h.p. Salmson engine, whereas the one at the Paris Show had a Renault engine. Also the tail planes have been slightly altered, so that now the rudders are mounted on and move with the elevator. The machine is built of steel almost throughout, and is mainly characteristic on account of its rather unusual type chassis, which consists of two stub axles universally pivoted to the rear end of the very long ash skid, and carrying two large diameter wheels which are sprung by means of rubber shock absorbers attached to telescopic tubes running from the outer end of the stub axle to the rear end of the lower longerons of the nacelle. The front end of the skid is supported on a structure of three steel tubes. Two smaller wheels mounted on a short tubular axle, prevent the machine from turning over on her nose on landing. The nacelle is built up in the usual way, and provides accommodation for pilot and two passengers, the latter being seated side by side between the pilot's seat and the leading edge of the wings. A wind shield in the nose of the nacelle deflects the air above the heads of the occupants. Behind the passengers' seat and inside the nacelle is mounted a large petrol tank, containing a supply sufficient for a flight of 4^ hours' duration. The engine, an 80 h.p. Salmson, is mounted between double bearings in the rear of the nacelle, and drives through a spur reduction gearing the large diameter pro- "Flight" Copyright.
