Description

The FlightGear Preconfigured 6DoF Animation block lets you drive position and attitude values to a FlightGear flight simulator vehicle given double-precision values for longitude (l), latitude (μ), altitude (h), roll (ϕ)、沥青(θ), and yaw (ψ), respectively.

The block is configured as a sim viewing device. If you generate code for your model using金宝app®Coder™and connect to the running target code using external mode simulation, Simulink software can obtain the data from the target on the fly and transmit position and attitude data to FlightGear. For more information, seeUse C/C++ S-Functions as Sim Viewing Devices in External Mode.

The Aerospace Blockset™ product supports FlightGear versions starting from v2.6. If you are using a FlightGear version older than 2.6, the model displays a notification from the Simulink Upgrade Advisor. Consider using the Upgrade Advisor to upgrade your FlightGear version. For more information, seeSupported FlightGear Versions.

Model Examples

HL-20 Project with Optional FlightGear Interface

HL-20 Project with Optional FlightGear Interface

This project shows how to model NASA's HL-20 lifting body with Simulink®, Stateflow® and Aerospace Blockset™ software. The vehicle model includes the aerodynamics, control logic, fault management systems (FDIR), and engine controls (FADEC). It also includes effects of the environment, such as wind profiles for the landing phase. The entire model simulates approach and landing flight phases using an auto-landing controller. To analyze the effects of actuator failures and wind gust variation on the stability of the vehicle, use the "Run Failure Analysis in Parallel" project shortcut. If Parallel Computing Toolbox™ is installed, the analysis is run in parallel. If Parallel Computing Toolbox™ is not installed, the analysis is run in serial. Visualization for this model is done via an interface to FlightGear, an open source flight simulator package. If the FlightGear interface is unavailable, you can simulate the model by closing the loop using the alternative data sources provided in the Variant block. In this block, you can choose a previously saved data file, a Signal Editor block, or a set of constant values. This example requires Control System Toolbox™.
Open Example

Algorithms

The block is a masked subsystem containing principally aPack net_fdm Packet for FlightGearblock set for 6DoF inputs, aSend net_fdm Packet to FlightGearblock, and aSimulation Paceblock. To access the full capabilities of these blocks, use the individual corresponding blocks from the Aerospace Blockset library.
