Stall strips

Slow-Speed Flight, Stall and Spin, and AOA System

T-45A/C TS, E2-C2, ADV & IUT Aero-03

Reduce boundary layer growth by reenergizing

boundary layer

NOTE: The vortex generators were installed on the

T-45 to help airflow characteristics during high-

speed (high Mach) flight. However, they also

improve slow-speed airflow characteristics.

Stall strips

Sg 1, fr 13

Fig 5: Stall Strips

Located on inboard slat and wing leading edges

to improve stall characteristics of the aircraft

Cause a premature flow separation at the wing

root, contributing to a root stall.

Slow the outward progression of stall

Contribute to more consistent root stall at all

flap/slat settings

Improve handling qualities at stall by controlling

roll-off

Do not reduce maximum lift coefficient

Stabilator vanes

Sg 1, fr 14

Stabilator Vanes

Located on both sides of fuselage, just forward

of stabilator and above speed brakes

Generate a vortex which passes below the

stabilator

Vortex energizes flow over stabilator lower

surface, keeping it effective, particularly at

maximum leading-edge-down stabilator

deflection

NOTE: The overall effect of high-lift devices is to

cause the root to stall at a lower AOA than the tip,

thus giving the T-45 root stall characteristics.
