Wing Weight Function

Description:

Dimensions: 10

The Wing Weight function models a light aircraft wing.

The response is the wing's weight.

Input Domain:

The input variables and their usual input ranges are:

Sw ∈ [150, 200]	wing area (ft2)
Wfw ∈ [220, 300]	weight of fuel in the wing (lb)
A ∈ [6, 10]	aspect ratio
Λ ∈ [-10, 10]	quarter-chord sweep (degrees)
q ∈ [16, 45]	dynamic pressure at cruise (lb/ft2)
λ ∈ [0.5, 1]	taper ratio
tc ∈ [0.08, 0.18]	aerofoil thickness to chord ratio
Nz ∈ [2.5, 6]	ultimate load factor
Wdg ∈ [1700, 2500]	flight design gross weight (lb)
Wp ∈ [0.025, 0.08]	paint weight (lb/ft2)

Modifications and Alternative Forms:

For the purpose of input variable screening, Moon (2010) adds 10 input variables.
