Science Visions Fa Faster aster ter Flight t With Vertical Rise Descent NEW YORK Jan 25 The 25 The possibility of m manufacturing nu flying machines which would rise and descend v vertically and yet be able to today's swift airplanes airplanes' was described today to of the country's outstanding aeronautical engineers rs Professor or Montgomery Knight of th the Georgia School of Technology told in a paper prepared for presentation presentation presentation pres pres- before the Institute of Aeronautical Sciences of encouraging encouraging encouraging ing results he obtained in studies of the helicopter Long a subject for experiment the world over the helicopter only lately has received serious consideration consideration consideration consid consid- from commercial flying in In- It uses vertical thrust propellers propellers propellers pro pro- for ascent and descent in instead instead instead in- in stead of the flow of air over the conventional wing Exploration Urged A cleanly designed helicopter said Professor Knight may may be expected expected expected ex ex- to have a high speed performance performance per per- superior to that of the corresponding airplane having the same power This fact together with its ability ability ability abil abil- ity to move vertically appears to the writer to make the helicopter worthy of further study and development development development devel devel- in spite of its inferiority in inthe inthe inthe the climbing range Two other research engineers advised advised advised ad ad- the institute that windmill airplanes may be a solution to better better better bet bet- ter flight E. E Burke Wilo Wilford Wilford-of dof of the Penn Pennsylvania Pennsylvania Pennsyl Pennsyl- vania Aircraft syndicate Inventor of a type of forecast a atop atop atop top speed of miles an hour with witha a landing speed of 40 This will not allow vertical de descent descent descent de- de scent but will permit landings on very limited areas he said as well as make safe and easy almost any emergency landing The Wilford is La similar to the revolutionary auto gyro or flying windmill invented by the late Juan de Ia de-Ia la Cierva Unlike the helicopter the canopy of whirling blades is actuated bythe bythe by bythe the forward or downward motion of the flying machines not by a mo mo- mo- mo tor Wilford's machine differs from Cierva's in that the former h has blades more firmly rooted to its mast and mechanically feathered as they approach and retreat from the direction of flight A description of his the upper wing of which takes on characteristics in descent was given in a paper by Gerard P.
