Question: What is the purpose of vortex generators on an aircraft wing?
Answer options:
- To increase the speed of airflow over the wing
- To reduce drag at high speeds ✅ To delay airflow separation at high angles of attack, improving lift at lower speeds and stall characteristics
- To provide additional thrust during takeoff
Correct answer: To delay airflow separation at high angles of attack, improving lift at lower speeds and stall characteristics
Explanation: Vortex generators are small vanes on the wing that create small vortices, which help keep the airflow attached to the wing's surface at higher angles of attack, thus delaying stall and improving low-speed handling.
