In Memoriam

Klaas Willem Jonker
(Wilko)
† April 30, 2018

On Monday 30 April 2018, Wilko Jonker died after a long illness at the age of 58. He leaves behind a wife and two children. The Dutch military aviation and plastic modeling were his hobby and on this website he shared all the knowledge he has collected over the years. His hobby has been able to distract him from the persistent disease in his body until the last week of his life. The contacts with other hobbyists were a major support for him.

This website will be maintained by different people for as long as possible, so that other enthusiasts can continue to benefit from extensive content.

Nieuport 21 & 23

History

The Nieuport 17 was e development of the Nieuport 11 and was equipped with enlarged wings and a more powerful engine.
The Nieuport 16 was a first attempt to resolve the shortcomings of the Nieuport 11, especially the rather weak lower wing. It was equipped with a more powerful engine, but this resulted in a higher wing load and less maneuverability.
The Nieuport 17 referred more to the principles of the Nieuport 11, but had new designed strengthened wings with larger area. The lower wing proofed to tend to twist at higher speeds just as was the case with the Nieuport 11.
It was equipped with a 120 hp Le Rhône engine. Later the Nieuport 17Bis was released with a 130 hp engine.
The Nieuport 17, which made it maiden flight in January 1916, was armed with a fixed machine gun mounted on the upper wing. It climbed as fast and was as maneuverable as the Nieuport 11.
