Stalls - cfinotebook.net Said another way, a stall is a condition of flight in which an increase in AoA results in a decrease in lift Angle of Attack (AoA/Alpha;): angle between the relative wind and the chord-line of an airfoil; Critical AoA: the angle of attack whereby any further increase will result in a separation of airflow which results in a stall An Experienced Pilot Explains “Stall Speed" - PaulCraigRoberts.org - Paul Craig Roberts - Official Homepage An Experienced Pilot Explains “Stall Speed” ... In order to maintain the airplane’s altitude in a turn, the pilot must then pull back on the yoke and increase the angle of attack, so as to increase diagonal lift and thereby provide enough vertical lift component to maintain the aircraft at the same altitude. That vertical lift component ... Leading edge slot — Wikipedia Republished // WIKI 2 At an angle of attack above about 15° many airfoils enter the stall. Modification of such an airfoil with a fixed leading edge slot can increase the stalling angleIn aircraft other than specialist STOL aircraft, full-span slots have serious drawbacks because, to take advantage of the high angle of attack at the... Работа по теме: 080 Principles of Flight - 2014. Глава:…

Slots delay the stall by increasing the stalling angle of attack (called the critical angle of attack), often past 22 degrees. The Method - Moving Energy From The Bottom To The Top A wing stalls because the air moving across it's upper surface separates, causing a decrease in lift.

US5056741A - Apparatus and method for aircraft wing stall… Increased bluntness of said leading edge portion, or increased slot-gap width, creates a stall condition on an inboard portion of the wing which approximates, at increasing angles of attack, the lift and pitching moment changes … Aerodynamics and Theory of Flight, Forces of Flight, Lift… Increased weight requires increased lift and an increased angle of attack; therefore the critical angle of attack (stall) will occur at higher airspeeds.

However, up to a point, lift coefficient reaches maximum and drops significantly. The angle of attack in which the lift coefficient reaches maximum is the critical angle (in the graph above, they use the notation stall angle of attack instead, but it means the same thing).

This will increase the stall AOA by about Δαmax ≈ 9°, the zero AOA lift coefficient will drop by about .... αZL = zero lift angle-of-attack.
