Show NEW PRINCIPLE Heavier Than Air Machines for Aerial Navigation Ex Expected Expected Expected to Solve Problem Paris Oct 20 OA A new principle of aerial navigation with ma machines machines chines s has been employed in some recent experiments and gives promise of large results Instead of using planes on the box kites principle driven by a vertical propeller as is III the case In the aeroplanes of ot Santos Dumont and other experiment ors up to this time rotary horizontal planes are used In Other r words the gyroscopic principle is employed and the machine Is called the The theory theor Is that by employment of ot hori horizontal horizontal horizontal propellers the machine can be easily easIly easily ily lifted and lowered after the fashion of the old toy longitudinal motion being obtained by the forces of at gravitation grav by allowing the machine to dip and glide glido on Its planes in the same way that heavy birds soar St Andrews Cross Count De Dc Lambert believes that this Is the true solution of ot aerial flight but the honor of ot constructing the first ma machine machine machine chine on this principle belongs to Louis Breguet He has built a machine In the general form o a Saint Andrews cross each arm having at its extremity eight revolving paddles or propellers slightly Inclined These paddles pre present present present sent a total surface of or square metres and are revolved by a forty horsepower motor at the center of ot the cross where the pilot sits The total tota weight of ot the machine is kilograms In the preliminary trials the machine left the ground instantly when the motor was set in motion and was easily sustained In Inthe inthe Inthe the air with revolutions a minute When the motor was slowed down the descended gently Perfect equilibrium m was maintained Longitudinal flight has not yet et been at attempted attempted attempted tempted but the Inventor thinks It will wll willbe willbe be easy to t make kilometres an hour I |
