Skoda-Kauba Sk P.14

History of Skoda-Kauba Sk p. 14

When Allied aerial bombardment operations destroyed German infrastructure and war, the Luftwaffe responded with the "Emergency Fighter Plan" in July 1944. The move calls for German aircraft makers to develop economical, powerful armed fighter/interceptors to help turn the tide of air combat.

If enemy bombers could be stopped, Germany's war effort could have been saved, leading to numerous special projects and proposals late in the war - many of which were frustrated, although some survived long enough to see limited operational service.

Skoda-Kauba Sk p. 14 does not belong to the latter. It was developed when Czechoslovakia was still occupied by German overseers. The P.14 is a single-seat interceptor built around a ramjet propulsion scheme to achieve the required high performance.

The design is very compact and puts its pilot on the nose. Much of the interior is occupied by a ramjet system, with a pair of small main aircraft (mid-mounted) on the sides of the fuselage and a short tailstock that supports a vertical tail and pairs of horizontal stabilizers.

The design of this aircraft is attributed to Eugen Sanger (1905-1964), an Austrian aerospace engineer, who before the end of his career focused on body principle enhancements and ramjet technology.

Ramjets existed for decades before WWII, but further development of the subject was impossible until technological advances began to demonstrate all aspects of sound. The system is a subclass of jet aircraft, but has the inherent limitation that it cannot generate its own thrust at zero airspeed. Therefore, ramjet-equipped aircraft require an auxiliary propulsion system to "accelerate", i.e. a rocket/rocket engine.

Once the minimum operating speed is reached, the ramjet can take over thrust in the traditional sense.

In the Sk P. 14, the ramjet unit was located in a large cylindrical frame under the aircraft, sucking in the nose and exhausting under the tailstock. The powerplant was designed by Sanger himself. In order to prevent the fuselage of the interceptor from being too low and thus creating significant drag, the pilot had to lie prone on his nose, which was partially viewed by glass. Basic controls and a simple dashboard complete the cockpit.

The proposed weapon is a MK 108 series 30mm automatic cannon mounted on the rear spine of the fuselage and firing from the cockpit position.

The design of P. 14 has some operational limitations. It lacks room for a true retractable landing gear, so takeoff will be assisted by a tricycle and landing by a simple belly skid (retractable). The latter adds its own danger factor, but keeps the interceptor relatively simple in terms of construction and maintenance. Once the ramjet's minimum operating speed is reached, the launch program is abandoned. The plane will also have limited range, mostly due to thirsty engines and baby tech.

The view to the rear of the aircraft is also limited by the pilot's fuselage and prone position. The prone position also requires special training for pilots who are not used to flying the plane in this way.

Two forms of P. 14 were eventually created, the first product being P. 14. 01, as described above. The successor, the P. 14. 02, differed in that the fuselage was shortened and its wings were moved slightly forward to possibly improve control. In any case, the aircraft did not exceed a few complete parts until the end of the war in Europe in May 1945.

As such, the P. 14 went down in history as another "Luftwaffe" in the aviation history of WWII. If" item.
