MotoSwift Carbon Propeller

We use HIRTH F-33 – 28 HP engine with BRIGHT STAR SWIFT wings and cage. As it turns out we had a problem with it – we don’t have the appropriate propeller. No results either after searching to buy one. We consulted with our fellow pilots and I decided to make my own propeller. The central part is milled from aluminum, the blade from composite materials. Sail plane manufacturer “AB Sportinė aviacija” at Pociunai airport made destructive tension test of the blade. After a month of strenuous work I had a three-blade 120mm diameter folding propeller that rotates counterclockwise. Weight 2.5kg. Pushing force about 60kgwith HIRTH F-33 at 5500rpm. I was satisfied after the first flight. The good results inspired our team to further design and improve the performance of the propeller. Pictures with red background are from destructive test performed at “AB Sportinė aviacija”. The bottom slide shows our future development. Yellow lines with numbers shows stages of our new designs.

Cockpit Fairings (Skin)

We developed new fuselage for our Brightstar Swift. New forms allows us to produce two part (bottom and engine cowl) fairings for standard Aeriane cage with the set of stronger wheels. Front wheel is not steerable, we think it is not necessary on big grass airfield like ours.

Integrated Cockpit

Because we don’t need to disassemble cockpit we can use composite materials and get rid of almost all metal parts. At the moment we are using chromoly tubes to hold the wings, but our vision is to make the cockpit from composite materials only.

Flaps Control

Total flaps handle movement distance is 30 cm (Brightstar swift has the same 30 cm due to less number of blocks for flaps line, therefore total flaps handle movement distance is 30 cm). We will also should have security system witch stops flaps movement if the handle is broken by brute pilot force or some accident. Also the spring witch holds the handle in the slots is mandatory.

Rocket Chute

While constructing we encountered a challenge – there aren’t many options of where to put ballistic parachute. We decided to put it behind pilots back and made a special container which serves as engine mount structure as well. We believe this is the best place for the parachute functionally, and for proper COG, we pushed the pilot forward and extended the nose of the fuselage forward.

MotoSwift Hirth Engine

In the pictures above you can see the engine, as well as cooling vents. Because the engine is behind pilot’s shoulders, there is not enough direct air stream for cooling, therefore we designed air intake vents (manual open/close). This system works well, however in the future we would like to use electrical fan induced air stream for engine head cooling.

Roller Cart

This is the early stages of our product – roller cart that has multi-directional movement and possibility to check COG by seating the pilot into flight position and pivoting fully assembled Aeriane Swift (including pilot, ballistic chute, instruments and fuel) on two pivots which rest on the ground at the COG position.
