Dornier Do 22

Dornier Seaplane Do 22.
From the Dornier Meta II, built by G. m. b. H., Friedrichshafen a. B., we present below a description of the previously unexhibited type,
the Do 22, a three-seat multi-purpose aircraft (maritime reconnaissance, bomber, torpedo aircraft) with two floats.
The wings are swept and slightly V-shaped, with parallel leading and trailing edges, rounded wingtips, two-spar, duralumin construction, and fabric-covered. Each wing is braced by
two stalks. The ailerons, with internal balance, can also be operated as landing flaps using a special device.
The fuselage is made of welded tubular steel. To achieve an aerodynamically favorable shape, duralumin frames and longitudinal profiles are attached to the fuselage frame, over which the fabric or metal skin is then laid. The crew entry openings, the engine cowling, and the firing port of the lower machine gun are covered in metal. The rest of the fuselage is covered with fabric. The pilot controls the main control stick, and the observer's auxiliary control stick. The pilot, observer, and gunner sit one behind the other. In addition to controlling the aircraft, the pilot operates the forward machine gun, which fires through the propeller circle. The observer operates the camera, the flight deck, and, in the event of a pilot incapacitation, the aircraft's auxiliary controls. The gunner operates the upper twin machine gun mounted on a rotating ring and the machine gun firing downwards from the lower firing port.
When used as a bomber, the observer is provided with the bomb-release device and the aiming device, which is mounted above the fuselage floor opening in place of the camera. If the aircraft is used for a torpedo attack,
the pilot is provided with the torpedo release device, while the second man in the rear position assumes the defense of the aircraft, both up and down, or is eliminated entirely.
The light-metal wing, divided into nine watertight compartments by eight bulkheads, is braced with steel tubes to leave space under the fuselage for the release of torpedoes and bombs.
The horizontal stabilizer passes through the fin and is braced to the fuselage by two steel tube struts and is braced to the fin by streamlined wires.
The horizontal stabilizer is adjustable by the pilot during flight. An auxiliary wing is mounted above the horizontal stabilizer to compensate for the elevator.
The rudder has a compensating flap at its upper end.
The propulsion is provided by engines with 700–900 hp. Main fuel tank capacity 640 liters with quick-drain valve in a compartment in front of the pilot. Two auxiliary fuel tanks of 100 liters each are located in the wing. Oil tank on the engine mount. Wingspan 16.2 m, length 13 m, height 4.72 m, wing area 45 m². Empty weight 2328 kg, standard payload 1022 kg, maximum 1672 kg. Maximum speed at full pressure with Hispano-Suiza Y: 320 km/h, landing speed 82 km/h. Climb time from
0–4000 m: 9 minutes, ceiling 9200 m. Maximum speed with Gnöme-Rhöne K 14: 325 km/h, landing speed 82 km/h, climb time to 4000 m: 8 minutes, ceiling 9300 m.
