Abstract:
The E67 design was for a vertical take off and landing
aircraft for executive use. Vertical flight capability was
achieved by using the tilt wing concept. In the initial
version of the design power was provided by two Rolls Royce
H1400 Gnome turbo shaft engines driving two 16 ft. diameter
propellers. Cross shaft interconnection between the propellers
was included in the layout. Subsequently the need for four
engines to cater for an engine failure condition in vertical
flight became apparent. The pressurised cabin was designed to
accommodate up to 18 passengers in a high density feeder role.
Conventional design techniques were used throughout.
A market survey showed that the design had significant
advantages relative either to a helicopter or a twin jet
executive type (Reference 3).
