gpkit-models

This repository contains those GP-/SP-compatible models that we consider well documented and general enough to be useful to multiple projects.

• Simple models with in-depth explanations (good for learning GPkit)
  • SimPleAC: a basic aircraft model that captures the fundamental design tradeoffs
  • Economic Order Quantity: tradeoff between setup and holding costs
  • Cylindrical Beam Moment of Inertia: GP approximation of cylindrical beam MOI
  • Net Present Value: financial tradeoff between cash and equipment
  • Raymer Weights: rule-of-thumb weight relations for aircraft design
• GP models
  • Aircraft
    • Wing Structural and Aero Models
    • Empennage: TailBoom, HorizontalTail, and VerticalTail inherit from the Wing model
    • Mission: models that unify subsystems and flight profiles
    • Fuselage: elliptical and cylindrical fuselage models
    • IC Gas Engine Model
  • Bending Beam: discretized beam for distributed loads
• SP models
  • Aircraft
    • Tail Boom Flexibility
    • Wing Spanwise Effectiveness
  • Atmosphere
    • Tony Tao's fits as (efficient) signomial equalities. Valid until 10,000m of altitude.
