negative damping foimd. It should be noticed that on this airplane the speed of the engine had quite a marked effect on the damping. The curves of period and damping for the JN^h are shown in Figure 10 for conditions of locked controls. The period on this airplane is affected by changes in airspeed… … Airspeed in Airspeed in h^.P.H. Fig. 9.—VE-7 with locked controls. Fig. 10.—JN4h with locked coatrols, stabilizer at —3.S7* and C. G. coefficieit yariation for the same range of airspeeds is 23 seconds to 70 seconds. This giv^ a range of period of nearly 10 to 1, which is considerably more than…
