Notes

The Engine class models an internal combustion engine’s performance characteristics including:

  • Sea level power rating

  • Power lapse with altitude

  • Fuel consumption characteristics

  • Power distribution capabilities

  • Operating speed effects

Major Assumptions

  • Constant power specific fuel consumption

  • Fuel properties remain constant

  • Steady-state operation (no transient effects)

Definitions

‘Flat Rate Altitude’

Maximum altitude at which the engine can maintain sea level power output

‘Power Specific Fuel Consumption’

Amount of fuel consumed per unit of power output per unit time

‘Power Split Ratio’

Fraction of total power delivered to primary load in multi-load applications
