Whigham GW-7 explained
The
Whigham GW-7 is an American mid-wing, single-seat, 15 metre class
glider that was designed and constructed by Gene Whigham, a retired
Convair flight test engineer.
[1] [2] Design and development
Whigham's last glider design was the GW-7. The aircraft was completed and first flew in 1987.
The GW-7 is of all metal construction, has a 151NaN1 wing span and employs a NASA NLF(1)-0215F airfoil. The flaps and ailerons are interconnected. The flaps travel +/-10° in normal flight in concert with the ailerons and then can be deployed to 60° for glidepath control on landing.[3]
Only one GW-7 was constructed and it was registered with the Federal Aviation Administration as an Experimental - Amateur-built.
Operational history
In July 2011 the sole GW-7 built was still on the FAA registry and owned by Donald Macey of Fallon, Nevada.
