Internal_Combustion_Engine#

class Internal_Combustion_Engine(*args, **kwarg)[source]#

Bases: Propulsor

A propulsion system class that combines an internal combustion engine with a fixed-pitch propeller.

engine#

The internal combustion engine component

Type:: None or Engine

propeller#

The fixed-pitch propeller component

Type:: None or Propeller

Notes

This class models a conventional propulsion system that pairs an internal combustion engine with a fixed-pitch propeller. Unlike constant-speed propellers, the blade pitch remains fixed during operation, making RPM directly dependent on throttle setting and flight conditions.

Key characteristics:

Simpler mechanical design than constant-speed systems
RPM varies with airspeed and power setting
Optimized for a specific flight condition
Lower cost and maintenance requirements

Definitions

‘Fixed-Pitch Propeller’: A propeller with blades set at a fixed angle, optimized for a specific flight regime (typically cruise)
‘Blade Angle’: The angle between the blade’s chord line and the plane of rotation, measured at a specific radial station
