Trailing Edge

The subject of trailing edge encompasses a wide range of important elements. What is the aerodynamic benefit of trailing edge sweep?. 11 Both leading and trailing edge sweep help to reduce compressibility effects. For simple estimates, quarter chord sweep is used. This is more influenced by the leading edge, but the trailing edge is still involved with 25% of the total value.

aircraft design - How critical is trailing edge geometry/sharpness on .... Since at the trailing edge you will find a several millimeters thick band of slow-moving air from the boundary layer, adding 0.5 mm from a thick trailing edge is not increasing drag significantly. aircraft design - Why are the trailing edges of wings not always made ....

From a purely aerodynamic viewpoint, you'd like the trailing edge of the wing to be absolutely razor sharp--something like a single atom thick would be your real ideal. But even if it's thin, material for a sharp trailing edge weighs more than material that simply isn't present. XFOIL - Modify the gap at the trailing edge of the airfoil. The trailing edge of my airfoil is too sharp, therefore leading to non-convergence of the analysis. Modifying the trailing edge thickness may do the trick. How to adjust the trailing edge thickness in XFOIL?

I read online that you have to use the command GDES > TGAP. However, I couldn't find anything regarding of what to input the command. From another angle, leading edge or trailing edge stall? - Aviation Stack Exchange. 3 The Benedek 10355 clearly stalls with separation starting from the trailing edge.

There is some discussion whether a laminar-to-turbulent transition due to rising pressure will always involve a laminar separation bubble, however short. But that bubble does not constitute a leading edge stall. Another key aspect involves, what is the difference between a leading edge flap and a slat?. In this context, both trailing edge flaps and LEDs (leading edge devices, be they leading edge Kreuger flaps or slats) increase camber in order to allow the wing to produce the same amount of lift at a lower airspeed (takeoff and landing). They do not increase lift; if they did the aircraft would go up (and slow down rapidly) which is not the point.

aerodynamics - Why do airfoil's trailing edges point downward .... The trailing edge of and airfoil is mostly pointing downward. Is there any reason for that? Down wash increases drag and down wash is due to the direction of air pointing down. If the trailing edge... This perspective suggests that, why does the F-15 have a swept-back trailing edge at its wing tips?.

Granted, trailing-edge sweep may be less common in a wing with a delta shape like the F-15's wing, but still-- Look at the planform view of the wing of the F-4 here.
