Characteristics of Thin Triangular Wings with Constant-chord Partial-span Control Surfaces at Supersonic Speeds


Book Description

A theoretical analysis was made of characteristics of constant-chord partial-span control surfaces on thin triangular wings at supersonic speeds by use in methods based on linearized theory for supersonic flow. Two cases were treated: In one the flap extended outboard from the center of wing and in the other the flap extended inboard from wing tip. Expressions were found for lift coefficient, rolling-moment coefficient, and hinge-moment coefficient due to flap deflection, hinge-moment coefficient due to angle of attack, and pitching-moment coefficient due to flap lift. A few figures are given to illustrate application equations.




Characteristics of Thin Triangular Wings with Triangular-tip Control Surfaces at Supersonic Speeds with Mach Lines Behind the Leading Edge


Book Description

A theoretical analysis, based on the linearized equation for supersonic flow, of characteristics of triangular-tip control surfaces on thin triangular wings. By restriction to case for which Mach lines from wing apex lie behind the leading edge, a simplified treatment was possible; results of previous work on lift of triangular wings could be used to derive expressions for lift effectiveness, pitching moment, rolling-moment effectiveness, hinge moment due to control deflection, and hinge moment due to angle of attack. Comparisons were made with two-dimensional case.
