Simulated Environment and Training

Use the j2 Universal Tool-Kit to develop high-fidelity flight models and use these in the complete range of simulated environments. Enhance pilot training in all areas, including G-Cuing, and enable pilots to experience the impact of planned changes to an aircraft’s handling characteristics at any stage in the design process.

The flexibility of the j2 Universal Tool-kit allows model developed with j2 to be used in the whole range of simulated environments, from desktop to full mission simulator platforms. Models built using j2 Builder can be analysed and assessed with auto-test capability using the j2 Freedom, j2 Virtual and j2 Visualize components of the tool-kit. These models can also be flown using the j2 Pilot plug-in without the need for the use to write any code of their own. This provides a significant reduction in effort and time for user to take their aircraft and to start flying instantly. All the flight dynamics and modelling capability of the j2 Universal Tool-kit is fully integrated with real-time pilot-in-the-loop capabilities of j2 Pilot. This takes aircraft models developed earlier (see detailed design), and provides and accelerated route to certification.

The j2 Universal Tool-kit is able to predict, in real time, aerodynamic changes and performance changes on any aircraft due to different stores configurations and stores release scenarios that will impact upon behaviour, manoeuvrability and performance.

The j2 Pilot software development kit (SDK) has opened up significant opportunity to drive a full range of simulator environments. This has enabled j2 to introduce full G-Cuing into Pilot training environments using authorised Martin Baker seats.

The actuators within the seat work in a coordinated way to provide simulated movement aligned to the pilot’s centre of gravity, which in itself is aligned to the aircraft primary axis X, Y and Z.

The actuators are stimulated from a complex 6-axis j2 flight model, which calculates in real-time equations of motion, based on the location of the pilot within the simulated aircraft model, for example, Hawk, Typhoon, and F35. This provides the pilot with ‘surge’, ‘heave’ and ‘sway’ cues. The j2 solution can accommodate the move from fixed base simulators to full G-seat simulators and incorporate a completely integrated and packaged simulator into advanced Pilot training, to cover such complex manoeuvres as strafing runs, flat spins, stores release and combat dog fighting against other aircraft in linked G-seat simulators.

The j2 Pilot SDK has proven the ability of the j2 Universal Tool-kit to assimilate into a multi-supplier simulation environment; it can be mapped to any simulation hardware platform from desktop to full mission environments. This application, derived from world-class aero modelling techniques, can be combined with accurate terrain mapping data to provide a step change in normal point-to-point mission planning. The j2 Mission planning tool set can have a Pilot fly a scenario in advance, expose potential operational weaknesses and test the viability of exit routes and other manoeuvres. This same capability can be applied to all areas of aircraft operations from civil to military.

Required Tools

  • The j2 Universal Framework is the core of the j2 Universal Tool-Kit. This provides the main data access, versaion control and configuration management. The j2 Universal Framework is required for all users. Aircraft models and Flight Test Or Simulation results can be automatically imported for use by the plug-ins.
  • Import designs/manufacturers models or create your own, using simple hierarchical data structure.
  • Detailed analysis of manoeuvres and handling of chosen design. Fly the Certification envelope. Increasing confidence in the aircraft’s ability to get Certified.
  • Detailed charts and templates can be created and re-used each time the model is refined to view consistent reports.
  • Understand the meaning in 3-D 360° outside world scenarios.
  • Take existing aircraft model code and engine data and integrate straight into the aircraft model through automated interfaces.
  • Engineer-in-the-Loop simulation enables the designers to fully understand the aircraft characteristics.
  • Take existing aircraft model code and engine data and integrate straight into the aircraft model through automated interfaces.
