FLIGHT, MARCH 6, 1931 THE NAVARRO "CHIEF" A Low-Power Three-Engined Monoplane Three^Seater pleted I HAT is probably thesmallest three-engined aeroplane in the worldhas just been com- at Heston by NavarroSafety Aircraft, Limited. Known as the Navarro " Chief." the newmachine is a three-seater fitted with three A.B.C. " Scorpion " engines.In addition, the aerodynamic de- sign is unusual in that it incorpor-ates a number of features which the designer, Mr. J. G. Navarro,believes will make the new machine immune from most of the evils towhich aircraft are subjected, such as stalling, spinning and side-slipping. Whether all these claims will be realised, remains to be seen.At any rate, Mr. Navarro has made a determined attempt to "go onebetter," and has not remained content to follow the beaten track.The aerodynamic features by which Mr. Navarro hopes to avoidstalling, spinning and sideslipping may possibly be seen most readilyin the general arrangement drawings on the next page. To take spinningfirst, it will be noted that the elevator flaps are hinged along axeswhich make an angle with the transverse axis of the machine.Mr. Navarro's theory is that, in a manoeuvre like the spin, the air THE NAVARRO " CHIEF " : Side and three-quarter rear views.
