Detailed Design and Analysis

Use the powerful j2 Universal Tool-kit to debottleneck the design process by providing all design disciplines with a common platform that minimises data transfer times and errors. Add further understanding and fidelity into your aircraft’s detailed design and analysis processes and reduce re-work.

The j2 Universal Tool-kit is used to accelerate aircraft development. The highly adaptable platform enables engineers from all disciplines in the design team to contribute ever more detailed data and analysis into the aircraft project.

All engineering disciplines access the same version controlled data sets with any updates and analysis results being recorded instantly into the embedded design version control. The integration plug-in, j2 Developer, allows design teams to merge data from any of their own code bases, higher order CFD or other data into the powerful modelling, simulation and performance engine.

Enable engineers to run multiple trade-off analysis in the same timeframe without adding manpower. Examine how subtle changes on the airframe can impact on aerodynamic performance and handling characteristics well before, during and after wind tunnel assessment. This adds significant value return from any wind tunnel project time.

The j2 Universal Tool-kit gives aircraft manufacturers a unique opportunity to introduce both hardware and Pilot-in-the-loop capability at any stage, to build further fidelity into the model and fly standard manoeuvres with a view towards certification (see simulated environment and qualification/certification).

The j2 Universal Tool-kit also allows engineers to better define objectives and test requirements for wind tunnel programmes. This can help to enhance the value return of any wind tunnel activity.

By proving the relationship between actual results and predictive model, the j2 Universal Tool-kit opens up potential for engineers to conduct further analysis and rapid trade/sensitivity studies, generating instant results without returning to wind tunnel. Planned airframe variations can be examined and mid-life upgrades evaluated much earlier in the aircraft lifecycle, looking at aerodynamic performance and actual behavioural characteristics.

The proven predictive model derived from your details design and analysis can be exposed to the j2 real time visual evaluation environment by using the j2 Virtual plug-in. The level of understanding this provides is unique and can be extended to include multiple overlays flying the same manoeuvre. This provides the capability for early intervention of engineers and Pilots to run certification manoeuvres, fly off different design configurations, and optimise designs before making the expensive move to wind tunnel. The virtualisation capability provides a profound 360-degree view of the aircraft in flight and , when coupled with the j2 Pilot plug-in, can use the same models to run desktop through full mission simulator by means of the j2 Pilot software development kit (SDK). This provides the opportunity to ‘test fly’ an aircraft well before certification and pre-production.

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.
  • Evaluate the aircraft models using Classical Linear Analysis.  Automatic Identification of Standard Modes of Motion, Frequency and Damping characteristics.
  • Evaluate complete set of performance charts. Evaluate the impact of altitude and airspeed on range and performance.
  • 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.
