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 when loitering, and then to retract this balloon to provide a high speed dash to a new location.

The company had investigated a variety of options when considering the feasibility of this project, none of which were able to provide a suitable modelling environment when considering evaluating the behavioural characteristics of the aircraft. They then approached J2 Aircraft Dynamics and we confirmed that through the use of the J2 Universal Tool-Kit we would easily be able to evaluate their design.
