WebAir flowing over any swept wing tends to move spanwise towards the rearmost end of the wing. On a rearward-swept wing this is outwards towards the tip, while on a forward-swept wing it is inwards towards the root. As a result, the dangerous tip stall condition of a rearward-swept design becomes a safer and more controllable root stall on a forward … WebMar 31, 2024 · For straight wings this speed is relatively low since all the air flows over the wing. Swept wings use their shape to redirect part of the airflow along the front edge of the wing (called span wise flow), and this reduces the amount of air flowing over the wing. This increases the critical Mach number since less air is present to create a ...

"WebLongitudinal instability results when the angle of attack of a swept wing increases to the point of tip stall. The instability takes the form of a nose-up pitching moment, called pitch-up, and is a self-stalling tendency in that the angle of attack continues to increase once the instability has set in. The aerodynamic causes of pitch-up are detailed in the following … " - Flexure of a rearward swept wing

WebNov 16, 2003 · The aerodynamic center of the wing is very near 25% of the mean aerodynamic chord of the wing. For trim it is necessary for the moments about the CG to be zero. This is normally achieved by wing twist in a swept wing, airfoil trailing edge reflex and by elevator trim position. WebThis part has the highest wing load and will stall first, while the swept back outer wing area - thanks to its profile, lower AoA and lower load will not have stalled yet. The nose drops, and the control surfaces in this rearward part stay functional. It should be noted that not all flying wing designs did achieve a safe stall behavior.
