The Hall Ibex is an experimental, American, gull winged, single seat glider that was designed by Stan Hall and first flown in 1968.[1][2]
Design & Development
The Ibex was designed by Hall to investigate the reduced wetted area of the pod and boom configuration, hands off spiral stability of a gull wing, and the low speed performance of wide NACA slotted flaps. It also features a V tail, Шаблон:Convert of water ballast and a Шаблон:Convert wingspan to comply with FAI Standard Class rules.[3] On one of its first flights the Ibex showed significant tail flutter. Initially Hall considered replacing the tail with a conventional empennage and tail[4] but ended up moving the ruddervator counterweights from the tips to the roots which eliminated the problem.[5]
Operational history
The Ibex was still flying in 1980 and was eventually donated to the National Soaring Museum.[6]
