Cost benefits of aerodynamic data generation techniques for aircraft stability and control analysis using the J2 Universal Tool-Kit
In modern aircraft development, effective stability and control analysis running parallel to the aircraft design is essential to the success of the manufacturer. Numerous aircraft manufacturers have had to spend large amounts of resources and time over the years as … Continue reading
Relative roles of computational fluid dynamics and wind tunnel testing in the development of aircraft
Much is talked of Computational Fluid Dynamics (CFD), concerning its role in the possibility of bringingdown the costs and turn-around times in the design and development of aircraft. Views have been expressed, at one extreme end, that wind tunnel testing … Continue reading
Flight Dynamics Analysis with J2 Aircraft Dynamics and the J2 Universal Tool-Kit
This document is intended to give a brief outline of the way in which the J2 Universal Tool-Kit can be used to assess any aircraft at any point in its design cycle from concept to completion and beyond. Each stage … Continue reading
The J2 Universal Tool-Kit – More than Dynamic Modelling
Jane’s “All the World’s Aircraft” has documented over 950 aircraft projects from over 550 manufacturers across the globe. In performing it’s market research to develop requirements and understand the industry perspective on software design tools, J2 Aircraft Dynamics have spoken, … Continue reading
j2 Project Example – Hoverwing Stability Analysis
Investigations were carried out using dynamic modelling techniques. This method builds a data model of the aircraft representing, as accurately as possible, both the aerodynamic characteristics and the structural characteristics to enable “simulations” to be performed. These simulations can be … Continue reading
Preliminary Analysis of an Aircraft Capable of Deploying and Retracting a Helium Balloon for Long Term Hover
J2 Aircraft Dynamics were approached by a company who were interested in the development of a UAV with exceptionally long endurance as an observation platform. The way of achieving this endurance, was to deploy a helium balloon to provide buoyancy … Continue reading
G Seat Press Release Background Material
EDM are one of a select 2 or 3 companies in the World who manufacture simulated ejection seats that are used in a variety of ilitary applications. The applications range from maintenance technician training to highly complex fighter pilot training … Continue reading
The J2 Universal Tool-Kit – Dynamic Behaviour Analysis
From Steady State or Static Analyses, a lot of information can be gathered about the stability, behaviour and characteristics of the aircraft. However to investigate the aircraft further we need to look at dynamic behaviour. Dynamic analysis uses a technique … Continue reading
Comparison of Flight Test Data Using the J2 Universal Tool-Kit
When working with predictive methods and simulation, the question that always comes back is how accurate are the results, and how does the behaviour compare to real life? This becomes critical when developing future concepts and designs, in so far … Continue reading
