The ACME Anser was an amphibious twin-jet utility aircraft that was developed in the United States by Air Craft Marine Engineering in 1958.
The cantilever shoulder-mounted wing was to have been a two-spar structure with honey-comb upper panels, fibre-glass leading edges and light-alloy lower skins with boundary-layer suction and re-circulation over flaps and ailerons.
The tail unit was to have been a simplified light-alloy built-up structure with a plastic foam core mounting a V-tail and housing the retractable outboard motor.
[2][3] The crew and passenger sat in a pressurised cabin lined with urethane foam for sound-proofing, shock absorption and thermal insulation.
[2][3] The two Turbomeca based Continental Model 420 turbofan engines were mounted at the wing-root trailing edge adjacent to the fuselage, in easily removable engine change units, with fuel housed in wing leading edge, wing-tip tanks and a hull flexible bag tank.
