| CURVE 4 S.U. CARBURETTER KESTREL(Aero Engine) VI ENGINE CONSTANT SPEED THROTTLE CURVE FROM FULL THROTTLE COMPARED WITH KESTREL(Aero Engine) VI CARB. JETS SET IN BOTH CASES AT .540 PTS/HP/HR AT FULL THROTTLE. THE CURVE SHEWS THAT IF THE JETS OF THE S.U. CARB. ARE SET AT THE RATED BOOST POSITION 550 B.H.P. TO .520 PTS/HP/HR. (W.M.M.P.) THE MIXTURE WEAKENS OFF AS THE THROTTLE OPENING IS INCREASED, TO MAINTAIN RATED BOOST ON A CLIMB, TO FULL THROTTLE HEIGHT. AXIS LABELS: Y-AXIS: SPECIFIC CONSUMPTION PTS/HP/HR X-AXIS: B.H.P TOP-AXIS: THROTTLE, FULL CURVE LABELS: S.U. CARB. S.U. CARB SET AT RATED BOOST KESTREL(Aero Engine) VI CARB.
