slide21

ORION AEROSPACE

Control Surfaces

slide22

ORION AEROSPACE

Aerodynamic Effectiveness of the control surfaces

Rudder Effectiveness: 60%

Elevator Effectiveness: 60%

Aileron Effectiveness: 30%

Effectiveness determined from Roskam’s Flight Dynamics and Controls

slide23

ORION AEROSPACE

Stability Derivatives

-Theoretical Method: This was presented on Tuesday.

-Will be compared to CMARC

CMARC needs:

-working wake

-will use to verify theoretical derivatives
