compute_wing_weight(vehicle, wing, WPOD, fidelity, settings, num_main_wings)

Calculate the wing weight based on the flops method. The wing weight consists of:

• Total Wing Shear Material and Control Surface Weight

• Total Wing Miscellaneous Items Weight

• Total Wing Bending Material Weight

Assumptions:

Wing is elliptically loaded Gloved wing area is 0 Load between multiple main wings is distributed equally Wing sweep is fixed

Source:

The Flight Optimization System Weight Estimation Method

Inputs:

vehicle - data dictionary with vehicle properties [dimensionless]

-.reference_area: wing surface area [m^2] -.mass_properties.max_takeoff: MTOW [kilograms] -.flight_envelope.ultimate_load: ultimate load factor (default: 3.75) -.systems.accessories: type of aircraft (short-range, commuter

medium-range, long-range, sst, cargo)

-.fuselages.fuselage.width: width of the fuselage [m]

-wing: data dictionary with wing properties

-.taper: taper ratio -.sweeps.quarter_chord: quarter chord sweep angle [deg] -.thickness_to_chord: thickness to chord -.spans.projected: wing span [m] -.chords.root: root chord [m] -.tip.root: tip chord [m] -.twists.root: twist of wing at root [deg] -.twists.tip: twist of wing at tip [deg] -.flap_ratio: flap surface area over wing surface area

-.networks: data dictionary containing all propulsion properties

-.number_of_engines: number of engines -.sealevel_static_thrust: thrust at sea level [N]

WPOD - weight of engine pod including the nacelle [kilograms] fidelity - “simple” or “complex” depending on the wing weight method chosen

Outputs:

WWING - wing weight [kilograms]
