Takeoff/stall tests today w/VG's...
OK.. for those who may be interested..
PA 28 -151 Warrior, Mattison seals & VG's, AMD upswept tips, K2U Root fairings...... TOW 1986 (28 gals) Pres, 29.47 Rny 68 ASL, Paved ,330 deg Wind, 3 knts 080 Temp -6 Deg C Rolling start (Mattison procedure) Flaps down (25deg) at 40 knts Wheels off rny, 450-475 feet, watched the 500 ft rny marker go under 10+ feet below us. Repeatable. At 3000 ft, Pwr off stalls with full flaps, and 2 knotches, confirmed at 40 knts indicated Stall with 2 notches flap, full power,(simulated departure stall) - aircraft seems to "hang" on prop shaking badly with a boot full of right rudder, yoke WAY back, stall horn yelping, but no break. Relaxed back pressure, instantly steady and climbing again. With this load/wind, we are now adjusting our approach speed down by 4 knts and IF I planted on the numbers, moderate braking (no squeaking the tires) stopped us before the 500 ft rny marker every time. Some expirementing .. if I could get the stall horn to start to squeak at the threshold I could lessen the "float" through the flare and touching down with the horn on. Stopped that time about 450 ft. Sure is a different airplane! Dave |
