An engine producing 230-lbs.ft of torque with a stock camshaft will produce a 2,000 rpm stall speed when a 2,000 stall speed converter is used. That same engine with a longer-duration cam will produce less torque, which also lowers your necessary stall speed.

Webb24 aug. 2024 · A high-speed stall is caused by shockwave formation. Because of the drastic changes that are brought to the airflow by the presence of a shockwave, it causes flow separation right behind it. A shock that is attached to the wing consequently causes the airflow to separate from the wing, and this leads to loss of lift. Webb3 apr. 2024 · Boeing 747-8. The Boeing 747-8 was first manufactured in 2008, and it continues to be produced today. When it was first introduced in 2008, the 747-8 variant cost $315 million or $405 million in today’s money. Presently, the official price of a Boeing 747-8 costs $418 million. WebbThe speed we are particularly interested in, with regard to maximum rate turns, is V A (see Figure 1).. V A is the maximum speed at which the pilot can make abrupt and extreme control movements and not overstress the aeroplane's structures. Above V A and the aeroplane can be overstressed before it stalls. Below V A the aeroplane will stall before … download thunderbird version 60
