Drag

This package contains the methods for calculating the drag of an aircraft. These methods are used across a variety of analyses (VLM, AVL, etc.).

Modules

asymmetry_drag(state, geometry[, ...])	Computes asymmetry drag coefficient due to engine failure and resulting trim requirements.
compressibility_drag(state, settings, geometry)	Computes compressibility drag coefficient for full aircraft including volume drag effects.
compressible_mixed_flat_plate(Re, Ma, Tc, xt)	Computes the compressible skin friction coefficient for a flat plate with mixed laminar-turbulent boundary layer.
compressible_turbulent_flat_plate(Re, Ma, Tc)	Computes the compressible skin friction coefficient for a fully turbulent flat plate.
cooling_drag(state, settings, geometry)	Computes cooling drag coefficient based on heat exchanger operation and air flow through cooling ducts.
form_drag(state, settings, geometry)	Computes the form drag coefficient associated with aircraft geometry and angle of attack.
induced_drag(state, settings, geometry)	Determines induced drag coefficient for the full aircraft using multiple calculation methods.
miscellaneous_drag(state, settings, geometry)	Computes the miscellaneous drag coefficient associated with aircraft components and configurations.
parasite_drag_fuselage(state, settings, fuselage)	Computes the parasite drag coefficient for a fuselage or boom accounting for compressibility effects.
parasite_drag_nacelle(state, settings, geometry)	Computes the parasite drag coefficient for all nacelles in the aircraft.
parasite_drag_pylon(state, settings, geometry)	Computes the parasite drag coefficient for pylons as a proportion of nacelle drag.
parasite_drag_wing(state, settings, geometry)	Computes the parasite drag coefficient for wings accounting for segments and compressibility effects.
parasite_total(state, settings, geometry)	Computes the total parasite drag coefficient by summing contributions from all aircraft components.
total_drag(state, settings, geometry)	Computes the total drag coefficient by summing all individual drag components.
trim_drag(state, settings, geometry)	Computes trim drag and updates aerodynamic coefficients due to control surface deflections.
windmilling_drag(geometry, state)	Computes windmilling drag coefficient for turbofan engines in windmilling condition.
