I. Overview

Many users are faced with the common problem of how to build a high-fidelity aircraft system simulator in the absence of real data, which can be used to construct an aircraft sequence trainer or a test bed for specific avionics equipment, in addition, they face stringent requirements such as trainer certification. In this scheme, COTS products are used to develop the avionics simulation system to meet the application requirements.

II. Contents of the proposal
　　

2.1, AIRCRAFT SYSTEM MODEL:

The problem of generating avionics model by software

1. Purpose of the model: It is often the case that the budget required for high fidelity training far exceeds the budget required for simulation training

2. Hardware selection: the hardware selection should also match the project requirements.

3. Software Selection: the software should match the hardware, and the software provider is primarily responsible for system integration

4. DATA: Some overall performance metrics can be pre-defined, even if a complete packet can not be obtained

5. Delivery time: is system delivery time also a rigid metric or is it elastic?

6. Funding budget: On the one hand with the option 1-5 above, on the other hand depends on the initial budget of the project

The FlightSim/HeliSim software of Presagis is used to develop the subsystem model of the aircraft. FlightSim software provides a very complete aircraft model. We can also modify and extend the model for different aircraft models based on the original system model. Models that are not part of the software itself, such as the GPS model, have been developed and are available.

The simulator is also built with reference to the overall performance of the aircraft, such as the flight curve, including take-off/landing (speed) ratio, turning speed, take-off speed and cruise speed, stall speed and so on. We use FLIGHTSIM and Helisim of prepgis to develop aircraft models, complete calibration and testing, and VAPS XT to develop the human-machine interface, through specific testing (Cooper-Harper experimental method) and human-machine interaction (pilot experience modification) , finally, an aircraft model for flight testing is completed.

2.2, data bus:

The use of DDS data bus for internal and external data communication of avionics system can greatly reduce the development workload based on DDS communication by using encapsulated RTI middleware, at the same time, the system can be easily aligned with the HLA simulation environment provided by the external environment generator (software such as Stage, Mak, VBS2, etc.) .

2.3, SCENARIO AND THIRD PARTY SOFTWARE INTEGRATION:

The solution can be integrated with prepgis STAGE, Vega Prime, Mak VR-Force, VR-Vantage, VBS2, Google

Scenarios such as Earth and computer force simulation software can simulate day and night flight environments. If it is used for avionics training or Fire Control System Training, IOS instructor board and SCORM learning system can be configured.
