The Aero Ae.04 biplane fighter succeeded the abandoned Ae.02 series though, again, only one flayable prototype was made.
Detailing the development and operational history of the Aero Ae.04 Single-Seat Biplane Fighter Prototype. Entry last updated on 6/21/2018. Authored by Staff Writer. Content ©www.MilitaryFactory.com
Part of the Czech air service changes included installation of the German BMW IIIa 6-cylinder water-cooled inline piston engine of 185 horsepower (locally-made under license). This was used to drive the two-bladed propeller at the nose. The fuel tank was relocated to the fuselage and an automobile-style radiator was seated behind the propeller unit. The wings (unequal-span, I-frame struts) were retained from the earlier Ae.02 as was the single-seat, open-air cockpit and twin 7.7mm Vickers machine gun arrangement.
A first-flight was had in 1921 and performance included a maximum speed of 140 miles per hour (cruising speed of 115mph), a service ceiling of 20,000 feet and mission endurance window of one hour flight time. 16,000 feet cold be achieved in about fourteen minutes. The prototype claimed a new altitude record of 20,869 feet during its time aloft. Later in its life, the aircraft sported a revised engine cowl and chin-mounted radiator unit which revised the appearance of the nose considerably.
Beyond additional flight testing and an appearance at the 2nd International Aircraft Exhibition in Prague, the Ae.04 followed the Ae-02 into Czech air history by being superseded by another design, this becoming the Aero A.18 of 1923.
