Cutaway Chichester Miles Consultants “Leopard”, the ambitious project to create a tiny Executive Jet with capacity for 4 people including the pilot, had minimum dimensions not exceeding 7.62 meters in wingspan and 7.88 meters in length, with a curious cockpit that opened completely forward allowing access to its occupants (seen in the first MiG-21F and the F-35), in the first prototype it lacked pressurization but in the second it did have it, its control controls were a small lever located between the pilot's legs in both front seats, with power control in a console between both seats, its fuselage was a structure in light composites and fiberglass basically in the lower part, the fuel was located behind the cabin and under the compartment for the luggage, this is accessed through a hatch in the upper part of the fuselage, its drift was integral as were the tail surfaces that served as elevators and ailerons, the wing did not have ailerons but it did have trailing edge flaps from the fuselage up to almost two-thirds of the wingspan of each semiplane, as well as small compensators, the wing was in a middle position and a long tricycle landing gear, the nose gear was shorter and had two wheels with forward retraction.
This plane was presented in 1982 as a Mockup where it excited many for its futuristic lines. It would be powered by two Noel Penny Turbines NPT-301 jet engines with only 145 kg of thrust. Its development was slow due to the wait for the engines. were available and the promise of soon having a more powerful engine, the NPT-754 with 34 kg of thrust, made its first flight in December 1988, its pilot stating that he was lacking power but its performances were pleasant and without surprises, the NPT company went bankrupt without developing the promised engine, leaving the project without a suitable propellant, causing the firm to look for more powerful but equally compact alternatives, managing to obtain two new, more suitable Williams International FJX-1 engines that allowed the construction of a second. prototype now with a pressurized cabin and complying with the benefits projected from the beginning, especially the speed and flight altitude of 45,000 feet, it flew in 1996 but again the market interest and financial support to continue the development was lost. Its designer, Engineer Miles, also created a military training version with a tandem cabin that did not go beyond a model. This plane was ahead of its time and along with another failed proposal (which did not fly) the Foxjet, in this case not having the small engines that were planned to be used (these had been requested for exclusive use in US Forces cruise missiles). US navies)
I reiterate, it is important to say that it still looks futuristic today and was born at a time when, despite the push put in by the firm, it could not go beyond two prototypes that languish today, one in a museum and the other in the unspecified headquarters of a firm. as gatekeeper. motorbike
