A rare example of the Dutch designed Kolibrie helicopter. Around ten were built.

This strange looking helicopter is seen here in the Aviodome at Amsterdam Airport. It has since been moved to the Aviodrome at Lelystad.

PH-NHI first flight 29-May-1956 and registered Jul-1956, in 1964 to the Aeroplanorama museum at Schiphol and then PH-NHI cancelled Jan-1965 as permanently withdrawn from use, in Jul-1971 transferred to the Aviodome museum also at Schiphol, in 2003 to the Aviodrome museum at Lelystad, and later to the Luchtvaart- & Oorlogsmuseum Texel at Texel

Well visible here is the small petrol engine that is used to spin-up the rotor with the two ramjets

After a small petrol engine had spun-up the rotor, the Kolibrie was powered by two ramjets at the rotortips. The total number produced was 11 and a number of them were exported to Israel and the United Kingdom. They were mainly used for agricultural spraying

Small utility helicopter designed by the Netherlands Helicopter Industry. Previously PH-NGV. Exhibited at the original Aviodome at Schiphol.

A light helicopter of Dutch design, the Kolibrie was powered by rotor tip-mounted Kromhout ramjets. About ten H-3s were built for agricultural use. This is the prototype H-3, first flown in May 1956. Its H-2 predecessor, PH-NFT, is suspended from the ceiling.
