Company Profile

Profile

J2 Aircraft Dynamics Ltd is a UK based company that is sells its own proprietary software, the j2 Universal Tool-Kit, as a proven application tool in the following areas:

  • Aircraft design, modelling and analysis covering conceptual, preliminary and detailed design stages, qualification/certification and through this, legacy system knowledge protection and knowledge transfer.
  • Building of Dynamic Flight Models for fixed wing and rotary platforms across the full fidelity range including flight test data matched models for large and small Simulator Manufacturers.
  • Flight test risk assessment, flight test planning and flight test data matching for aircraft and simulator certification.
  • Air accident analysis, reproduction and scenario investigation.
  • PAV/eVTOL development, analysis and FCS development and evaluation

The j2 Universal Tool-Kit software is built as a single, sustainable, non-legacy framework. Engineers/designers are finding that using j2 Software can unlock value in existing legacy code blocks as well as accelerate the work process across the area of application. The state of the art aircraft modelling and tuning capability embedded in j2 software allows engineers to ‘fly’ their designs and put a pilot in the loop at a much earlier stage in any aircraft design process.

The j2 Universal Tool-Kit is a powerful framework which is already trusted and proven with global OEM’s, simulator OEM’s and Flight Test Data Matching companies. A chronology of the company business highlights can be found by clicking this link:

The software runs on a common Windows operating system that can be fully networked or used stand-alone. A key feature is that existing legacy code blocks and user defined data can be easily integrated within the j2 software framework, protecting knowledge that already exists and greatly enhancing both the speed and fidelity of the resulting analysis.

J2 validated whole aircraft models including external models built in other code, can be ‘flown’ in desktop to full mission level d simulators from conceptual design stages onwards, accelerating the design process and the move to certification. The j2 flight modelling capabilities within the j2 software can also be used to rapidly qualify changes to any aircraft, accelerating mid-life updates or evaluating the aerodynamic impact of proposed changes to external structures and have a pilot evaluate these prior to further wind tunnel time or actual flight test. Users of j2 software can analyse a much wider array of options/trade-studies rapidly from conceptual design through to detailed engineering stages and flight test.

In the world of aircraft design analysis, modelling and evaluation j2 Aircraft Dynamics is focused on accelerating the pace of progress, unlocking innovation in design and providing aircraft engineers/designers with the tools they need.

Products

The j2 Universal Tool-Kit is a powerful framework coupled with a fully integrated suite of plug-in modules covering the full range of design, analysis and modelling applications. The j2 framework and j2 plug-in environment is used to deliver the whole aircraft aerodynamic model building, design analysis, visualisation and simulation capability which can drastically reduce some areas of design and engineering evaluation life cycles. The j2 Universal Tool-Kit is already able to integrate with a variety of existing globally recognised environments e.g. MATLAB Simulink, low and high order CFD code and wind tunnel data and flight test data providing a truly powerful proposition. The company already has technical acceptance and user experience in its chosen application areas:

  • Aircraft design, modelling and analysis covering conceptual, preliminary and detailed design stages, qualification/certification and through this, legacy system knowledge protection and knowledge transfer.
  • Building of Dynamic Flight Models for fixed wing and rotary platforms across the full fidelity range including flight test data matched models for large and small Simulator Manufacturers.
  • Flight test risk assessment, flight test planning and flight test data matching for aircraft and simulator certification.
  • Air accident analysis, reproduction and scenario investigation.
  • PAV/eVTOL development, analysis and FCS development and evaluation

J2 Aircraft Dynamics Software offers aircraft design and simulation companies the opportunity to drastically cut work process cycle time associated with all its core areas of application summarised above.

Markets Served

J2 Aircraft Dynamics products are used throughout the global aerospace industry as fundamental tools for the design, analysis and modelling of fixed and rotary wing aircraft. The j2 products are fast becoming a standard for whole aircraft modelling into simulation in what is an increasingly demanding market segment.

The company has grown globally achieving technical and commercial acceptance with a large global players, like Embraer, L3Harris and TRU Simulation and Training and through strategic technical and commercial alliances with acknowledged technical leaders in their fields i.e. ESI Inc for air accident investigation.

The j2 Universal Toolkit software continues to grow in its capability and application and has evolved from its core aero engineering and design areas around advanced conceptual design, detailed design and analysis, component performance modelling and aerodynamic change evaluation into more advanced and valuable areas of application e.g. the j2 software is delivering substantial value return in the areas of flight test data matching/QTG development and compliance through the use of j2Flight and the newest addition, j2Rotary where the rapid delivery and tuning of high fidelity rotary models is now possible and the move into the PAV/eVTOL development market place.

j2 is regarded as a significant expert witness resource for certain air accidents and more information can be found by using this link: http://www.j2aai.com

j2 also recognises the importance of supporting colleges and universities around the world and provides free j2 Universal Tool-Kit software for teaching and research in aerodynamic design modelling and analysis disciplines.
