openap

The OpenAP performance model allows for using different types of aircraft and obtaining the performance results. For each aircraft type, parameters such as dimensions, limits, nominal cruise condition, and engine options are given.

OpenAP is one of the performance models available in Bluesky.

For more information refer to OpenAP: The open-source aircraft performance model and associated toolkit

Enable OpenAP

In settings.cfg select the following option:

# Select the performance model. options: 'openap', 'bada', 'legacy'
performance_model = 'openap'

Available Aircraft Types

Types of fix wing aircraft are defined in: Aicraft Types

For rotors aircraft, the types are defined in: Rotor Types

The name of each aircraft object identifies the name which should be used to create each aircraft type.
