C-Wolf Project visit

On Saturday 17 May, about 50 EAA Chapter 322 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. This is a really impressive project with brilliant engineering and thinking being invested in this innovative aircraft. Wolfgang and his son Stefan are members of EAA Chapter 322 Johannesburg. Wolf’s wife Cheryl supplied all comers with a delicious breakfast during the visit.

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-seat 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’s a Seabee?’ The C-Wolf bears a resemblance to the Seabee, but is somewhat bigger and of composite construction. It has been designed and built from scratch. Wolfgang spent 1400 hours designing and refining the concept and started building on the project in December 2008. Although the C-Wolf is still in the experimental stage of development, the commercial potential is obvious. There is a lot of interest from military and quasi-military authorities in the aircraft from several countries. During AAD 2012 the design even invoked requests for the aircraft’s manufacture to be moved to the Middle East which would ensure an initial 25 aircraft order.

The 1,8 ton C-Wolf can be configured for reconnaissance with a 12-14 hour endurance and be operable at 22,000’. 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 fitted. 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 as an option. 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 a 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. One of the EAA objectives is of course education in all forms of aviation endeavours. The camaraderie that exists during these excursions to the many aircraft projects that are under way by EAA 322 members is wonderful. EAA Chapter 322 has its own in-house build project where a Skyworx Teddy (J3 lookalike) is being built at Krugersdorp under the supervision of the Skyworx owner and our EAA Technical Officer, Kevin Hopper.
