Yep, dat is't. Maar wat is het?

The Boeing L-15 Scout or YL-15 was a small, piston engine liaison aircraft built by Boeing in very small numbers after World War II. It was a short take-off and landing (STOL) aircraft powered by a 125 hp Lycoming engine. The L-15 was an attempt by Boeing to expand its product line as World War II drew to a close and Boeing's production of combat aircraft declined. Boeing decided against marketing the L-15 as a general aviation aircraft, and the few that were produced went to the United States Army. Most were used in Alaska for various duties. (Wiki)

A liaison aircraft (also called an army co-operation aircraft) is a small, usually unarmed aircraft developed before World War II and primarily used by military forces for artillery observation or transporting commanders and messengers. The aircraft were also used for battlefield reconnaissance, air ambulance, column control, light cargo delivery and similar duties. Able to operate from small, unimproved fields under primitive conditions, with STOL capabilities, most liaison aircraft were developed from, or were later used as general aviation light planes. Today, the helicopter performs the duties formerly accomplished by liaison aircraft. (Wiki)

The Comper Streak

The single seat sports monoplane was originally designed to compete in the ill-fated International Air Races. Comper decided to enter the Streak for the 1934 Coupe Deutsch and work on the plane began in earnest in late 1933. The Comper Aircraft Company realised that the Swift was reaching the end of its life and needed a replacement.
When the Streak emerged from the Heston workshops it looked for all the world like a low-winged Swift with a retractable undercarriage. Comper installed a high compression 146 hp Gipsy Major engine of only 6.1 litre capacity and unsupercharged. Its maiden flight was on 12th April 1934. The trial was marred by major structural problems with the ailerons. They stayed intact but on landing it was possible to see that for every aileron a hinge eye-bolt had sawn a vertical slot in the rear spar web. Disaster was narrowly averted.
The Streak received its air worthiness certificate on 18th May 1934 and as planned was entered at Etampes. But in the second round of the competition its undercarraige failed to retract and it was retired after six laps. It appeared again in the King’s Cup of that year at Hatfield. Comper was forced to retire the plane after the first round after it had failed to reach its handicap speed of 180 mph.
By now the Comper Aircraft Company’s financial troubles had come to a head. The new company that replaced it, Heston Aircraft Company (in which Comper was not a part) struggled on. In 1935 the plane made its last public appearance at the King’s Cup air race. After that it faded into obscurity and was finally scrapped in 1937

Helemaal goed Johannes. In het tijdschrift flight (1934) is beschreven dat de flutter als een grote verrassing kwam omdat de vleugel juist erg stijf was. Door toepassing van de gewichtjes en door verkleining van de koorde van de ailerons werd het flutterprobleem opgelost.

Dit voor de races gebouwde toestel werd snel opgevolgd door de meer all-round tweezitter Kite.

Nieuwe opgave

De uitvinder en piloot van dit toestel koos voor een engineering studie in Duitsland.
In Duitsland bouwde hij vier vliegtuigen. Het plan was om met zijn fabriekje te verhuizen naar zijn geboorteland. Maar dat werd hem daar door de overheid geweigerd.
Toen emigreerde hij naar een land wat openstond voor starters.
Daar kon hij zich volledig richten op het ontwikkelen van vliegtuigen.
Het toestel in deze opgave was een uitstekend ontwerp met een aantal belangrijke uitvindingen. Een van deze uitvinding vind je terug in een aantal hedendaagse hypermoderne toestellen.
