Powerplant Strategies

The Powerplant properties group describes the aircraft's propulsion performance using one of several empirical models of aircraft engine systems.

Electric

The Electric strategy models an electric engine.

ParametersClosed

Field Description
Max Power Defines the maximum power of the engine.
Propeller(s) Defines the physical properties of the engine's propeller(s).

External Prop File

The External Prop File strategy uses aerodynamic data supplied by a .prop file.

ParametersClosed

The File Path field displays the currently selected file; click to browse to the file that you want to use. You can review the data in the file by selecting from a variety of data plots available from the drop-down menu at the upper right of the window. You can use the Throttle Tuple property to adjust the range of data that is displayed in the plots. Click anywhere in the profile to view information about the aircraft's performance in the Data at point properties group.

Click Create Copy... to save a copy of the file to your catalog file area, which is the default location that Aviator opens when you select a .prop file to use.

Piston

The Piston strategy models a piston, or reciprocating, engine.

ParametersClosed

Field Description
Max Sea Level Static Power Defines the maximum static power of the engine at sea level.
Critical Altitude Defines the engine's critical altitude.
Propeller(s) Defines the physical properties of the engine's propeller(s).
Fuel Flow Select Calibrate Fuel Flow to edit the Fuel Flow at Max Thrust property. You can enter a new value for the property manually, or click Calibrate to open the Fuel Flow window and determine the value by adjusting the properties in the calculator; the value displayed in the Sea Level Fuel Flow field will be propagated to the Fuel Flow at Max Thrust field when you click OK.

Turbofan - High Bypass

The Turbofan - High Bypass strategy models a turbofan engine that produces significantly more fan thrust than jet thrust.

ParametersClosed

Field Description
Max Sea Level Static Thrust Defines the maximum static thrust of the engine at sea level.
Design Point Defines the Altitude and Mach Number that comprise the design point of the engine.
Fuel Flow Select Calibrate Fuel Flow to edit the Fuel Flow at Max Thrust property. You can enter a new value for the property manually, or click Calibrate to open the Fuel Flow window and determine the value by adjusting the properties in the calculator; the value displayed in the Sea Level Fuel Flow field will be propagated to the Fuel Flow at Max Thrust field when you click OK.

Turbofan - Low Bypass

The Turbofan - Low Bypass strategy models a turbofan engine that produces significantly more jet thrust than fan thrust.

ParametersClosed

Field Description
Max Sea Level Static Thrust Defines the maximum static thrust of the engine at sea level.
Design Point Defines the Altitude and Mach Number that comprise the design point of the engine.
Fuel Flow Select Calibrate Fuel Flow to edit the Fuel Flow at Max Thrust property. You can enter a new value for the property manually, or click Calibrate to open the Fuel Flow window and determine the value by adjusting the properties in the calculator; the value displayed in the Sea Level Fuel Flow field will be propagated to the Fuel Flow at Max Thrust field when you click OK.

Turbofan - Low Bypass Afterburning

The Turbofan - Low Bypass Afterburning strategy models a turbofan engine that produces significantly more jet thrust than fan thrust and has an afterburner.

ParametersClosed

Field Description
Max Sea Level Static Thrust Defines the maximum static thrust of the engine at sea level.
Design Point Defines the Altitude and Mach Number that comprise the design point of the engine.
Fuel Flow Select Calibrate Fuel Flow to edit the Fuel Flow at Max Thrust property. You can enter a new value for the property manually, or click Calibrate to open the Fuel Flow window and determine the value by adjusting the properties in the calculator; the value displayed in the Sea Level Fuel Flow field will be propagated to the Fuel Flow at Max Thrust field when you click OK.

Turbojet

The Turbojet strategy models a turbojet engine.

ParametersClosed

Field Description
Max Sea Level Static Thrust Defines the maximum static thrust of the engine at sea level.
Design Point Defines the Altitude and Mach Number that comprise the design point of the engine.
Fuel Flow Select Calibrate Fuel Flow to edit the Fuel Flow at Max Thrust property. You can enter a new value for the property manually, or click Calibrate to open the Fuel Flow window and determine the value by adjusting the properties in the calculator; the value displayed in the Sea Level Fuel Flow field will be propagated to the Fuel Flow at Max Thrust field when you click OK.

Turbojet - Afterburning

The Turbojet - Afterburning strategy models a turbojet engine that has an afterburner.

ParametersClosed

Field Description
Max Sea Level Static Thrust Defines the maximum static thrust of the engine at sea level.
Design Point Defines the Altitude and Mach Number that comprise the design point of the engine.
Fuel Flow Select Calibrate Fuel Flow to edit the Fuel Flow at Max Thrust property. You can enter a new value for the property manually, or click Calibrate to open the Fuel Flow window and determine the value by adjusting the properties in the calculator; the value displayed in the Sea Level Fuel Flow field will be propagated to the Fuel Flow at Max Thrust field when you click OK.

Turboprop

The Turboprop strategy models a turboprop engine.

ParametersClosed

Field Description
Max Sea Level Static Power Defines the maximum static power of the engine at sea level.
Propeller(s) Defines the physical properties of the engine's propeller(s).
Fuel Flow Select Calibrate Fuel Flow to edit the Fuel Flow at Max Thrust property.
