OCTOBER 26, 1922 THE PEYRET TANDEM MONOPLANE Details of the Winning Machine UNUSUAL as is the aerodynamic design of the Peyret tandem Everybody was " taken in monoplane, its construction appealed to all experts at the first glance, and even before the machine took the air it was conceded that, whatever peculiar views M. Peyret might have on the subject of disposition of wing surfaces, side areas, etc., he knew how to build a glider. The three-ply and before the start most of us expected to see the machine crash on the hill-side. No sooner was it in the air, however, than it became evident that here was a machine which had something that most of the others lacked, i.e., controllability to an amazing extent. That it was as efficient, regarded purely as a glider in still air, as m % 3?%^1FS ^ ^ SK is ss ^ The Winner: Bringing the Peyret mono plane up to the top of Firle Beacon. §g & ^ SS Si Si mahogany fuselage was evidently the work of an expert, and the wing bracing with one set of " N " struts on each side gave great rigidity in spite of evidently slender spars. Also, the differential control arrangement certainly looked extremely unlike what one would expect from an amateur enthusiast. Yet the fact remains that no one, ourselves included, really took the machine seriously until it had left the ground. It is useless to pretend that it was otherwise. some of the others might be open to doubt, but that the pilot did have abundant control could not be doubted for one moment. The short, sharp turns bore testimony to that, as did the fact that even the most vigilant observation of the machine failed to reveal more than the slightest move ment of the ailerons, indicating that at no time were the controls used to anything approaching their fullest extent. The rudder could be seen moving slightly from side to side. THE PEYRET MONOPLANE : Some constructional details. 1, View into the cockpit, showing controls and position of air speed indicator. 2, The differential control by which the flaps are operated as combined ailerons and elevators 3 and 4, Details of the wing bracing strut attachments. 5, One side of the undercarriage. The wheel has been omitted for the sake of clearness. 6, Front wing roots on fuselage. 7, Details of spar attachment to fuselage. Note metal-faced ply-wood wing roots, and quick-release bolts, 621
