Functions

Lift Coefficient Roll Control

The Lift Coefficient Roll Control is a dimensionless quantity that shows how much lift a lifting body creates relative to the fluid density, velocity, and an associated reference area.

Symbol: C_l

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Derivative of Wing Lift Coefficient

Derivative of Wing Lift Coefficient is the lift curve slope, which is a measure of how much lift changes when the angle of attack of an aircraft changes.

Symbol: C_lαw

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Flap Effectiveness Parameter

The Flap Effectiveness Parameter is a measure of how much flaps improve an aircraft's aerodynamic performance.

Symbol: τ

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Deflection of Aileron

The Deflection of Aileron refers to the angular displacement of the aileron control surface from its neutral position.

Symbol: δ_a

Measurement: AngleUnit: rad

Note: Value can be positive or negative.

Wing Area

The Wing Area, S, is the projected area of the planform and is bounded by the leading and trailing edges and the wing tips.

Symbol: S

Measurement: AreaUnit: m²

Note: Value should be greater than 0.

Wingspan

The Wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip.

Symbol: b

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Chord

The Chord is the distance between the trailing edge and the point where the chord intersects the leading edge.

Symbol: c

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Initial Length

Initial Length is a length between wing center to aileron start point.

Symbol: y₁

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Final Length

Final Length is a length between center of wing to the aileron end point.

Symbol: y₂

Measurement: LengthUnit: m

Note: Value should be greater than 0.

int

The definite integral can be used to calculate net signed area, which is the area above the x -axis minus the area below the x -axis.

Syntax: int(expr, arg, from, to)
