Enhance and update model fidelity, expand analysis to look into details giving increasing confidence in a chosen design. Look at the impact of data errors and tolerances to assess design sensitivity and key points in the envelope. Integrate higher order data into the models from CFD, Wind Tunnel or other code bases and rapidly evaluate the complete mission and flight envelope.

2. By proving the relationship between actual results and the 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 detailed 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 to full mission

opportunity to ‘test fly’ an aircraft well before certification and pre-production.
STANDARD APPLICATION
