We have been drafting a Q&D document on this topic: It shows that such airbag parachute design is feasible and can reduce rescue height considerably, shortening the opening time of the parachute. Comments of our advisors were that indeed they think it is interesting and particularly useful for paragliders. You can download the document in the about section.
Air Frame Progress
With Marko, one of the team members, a lot of progress was made on the first frame. We now have included the seating ass part of the frame. It really looks good. Next week we will present it in the blog. Personally I think it is a complete new concept, and is a pleasure for the eye, if one can say so.
Design of the belt drive
Here too we have made a first drawing on the belt drive. we plan to use a 50 mm width T10 belt for the connoisseurs. We used a Software programme to calculate stresses. This is a strong one and double the size of what can be seen in the paraglider sector. There belts of 25 to 30 mm are used. Of course this is all a matter of life time and wear.
In Hongkong, where Hobby King has its HQ, there was some delay in communication. So we hope this is soon solved so we can have the required parts.
Brushless E motors
There are some beautiful motors available in the market like Plettenberg, Hacker, etc that have low speeds and high power so no need for a gear belt reduction. These motors are however high cost. So we cannot use these. A first study on motors tries to see what is needed. see picture.
