Build your own HPA

How do you go about building your own HPA?

First join the BHPFC.

Research, research, research

Then do some research, read as much as possible, start at Publishing, Human powered flying and propdesigner.co.uk. It’s much too late to do your research after you have started building it.

Then think about talking to some people who have already built a HPA. They have done most of the stupid things already so you don’t have to find out  the hard way for yourself, not that you will believe them

Start doing some calculations to see what is required in terms of wing area and wing span to get a feel for the problem of designing a HPA. You will probably go through many iteration before you are happy with the design.

Then you are ready to start the design. There are designs out there for things like wing spars or whole planes or you can design your own.

The BHPFC is working on some designs for HPAs One based on Betterfly built mainly from Carbon fibre and another design based on standard Aluminium tubing for a reduced cost but slightly reduced performance HPA

Build the HPA

 This requires some space. As HPAs are normally built in sections, fuselage and 5 or 6 wing sections  the space required can be moderate, 5 or 6 metres long. It is only when you want to assemble the whole aircraft that there may be problems.

Simple! Well, not really. It can be a complex process but there is help and encouragement  on this site.

Fly your HPA

There can be a real problem of finding a place to fly. This is one reason for the BHPFC competition. It provides a place where you can try flying your design so even if you don’t win, you will be in  the company of other HPA enthusiasts who will encourage you.
