C-WOLF PROJECT UPDATE 17 MAY 2014

On Saturday 17 May, about 50 EAA members had the pleasure of visiting Wolfgang Vormbaum's engineering works in New Doornfontein to see the progress of his C-Wolf A.U.V. project. Wolfgang and his son Stefan are members of EAA Chapter 322 Johannesburg. We were all astounded at the engineering and brilliant thinking that is being invested in this innovative aircraft.

Wolfgang, who has never held a pilot's licence, is following a boyhood dream to build an amphibious family aircraft that could be used as a roomy air conditioned 6 seater family transport. When the C-Wolf concept was shown to fellow EAA members for the first time, many people said that it looked similar to a scaled-up Seabee. Wolfgang's reaction was a genuine 'What is a Seabee?' Although it bears a resemblance to the Seabee, it is a completely different concept, being completely of composite construction, designed and built from scratch.

The 1,8 ton C-Wolf can be configured for reconnaissance with a 12-14 hour endurance and be operable up 22,000 feet. Useable weight will be around 800kg. The prototype will be powered by the South African designed and built Adept 320T turbo intercooler engine driving a 5-blade MT reversible constant speed propeller. It is projected to provide a 120 knot economical cruise.

The aircraft is immensely robust. For slow speed, take-off and landing, slatted Fowler flaps are deployed. Pitch control is achieved with the moving surfaces of the canard and elevator. An all glass panel with three displays is ergonomically laid out and a ballistic chute will also be incorporated.

Hopefully, taxi tests will be possible in 6 to 12 months' time. The C-Wolf project is outgrowing its present nest and all work will soon have to be moved to new hangars that have been purposely built for the project at Syferfontein, also known as Baragwanath, the home of J.L.P.C.

It is a great honour for EAA to have innovators such as Wolfgang as a member. At Chapter 322, it is policy to visit different members' build projects monthly if possible, in order to encourage others and also for the members who have been there before and been involved in aviation professionally to offer advice/suggestions and learn from the complexities and techniques involved in these projects.
