Romanian Raul Oaida Reaches Fame With Stunning Invention: Jet-Engine Bicycle
19-year-old Romanian designed and build an original vehicle: “turbo-bicycle powered by a jet engine”! (scroll down for video and photos)
This appears to be the first Romanian jet engine in the last century – since Henri Coanda.
Taking a quick look on the web, you can find some details about Coanda. Well, “Henri Marie Coandă (7 June 1886 – 25 November 1972) was a Romanian inventor, aerodynamics trailblazer and builder of an experimental aircraft, the Coandă-1910 described by Coandă in the mid-1950s as the world’s first jet, a controversial claim disputed by some and supported by others. He invented a great number of devices, designed a “flying saucer” and discovered the Coandă effect of fluid dynamics.” (Wikipedia.org)
Before becoming famous abroad, Raúl has enjoyed appreciation also in his home country of Romania. What does he say now?
The novel vehicle would cost € 15,000 if sold on the market. However the guy from the city of Deva, Hunedoara county, uses the jet bike only for demonstrations, writes nou.zhd.ro.
The overall cost of the jet engine amounted to € 5,000. He received much of the amount from people who were surprised by his project after founding him on Internet.
The first sponsorship came from ARCA (Aeronautics and Cosmonautics Romanian Association), a non-profit organization running the Romanian Space Programme (2012-2025) and whose objective is the exploration and colonization of space.

Oaida’s engine weighs 5 kg and is made of duralumin, stainless steel, titanium and some alloys.
“The first jet engine weighed a ton and was very big. Mine is as big as a notebook and works like a Swiss watch,” says the inventor, explaining that he does not directly control the engine, but by a computer which picks up signals, analyzes them and then provides the necessary commands.
“If you try to manually start a jet engine, you can destroy it. A computer does what a human operator could never do. 20 years ago, this computer was as big as a refrigerator and cost 100,000 euros. My computer is the size of a matchbox and costs 200 euros. Technology said its word,” explains the young inventor.
The jet engine operates on a mixture of petrol, diesel and synthetic oil.
“Specifically: 4 parts diesel, one part gasoline (benzine) and 2 percent synthetic oil. That’s equivalent to kerosene which is difficult to find, and in case you are lucky enough, then you have to buy large quantities. At maximum speed – i.e, 93,000 rev / min (RPM), the engine consumes one liter per minute,” said Oaida for local newspaper Hunedoreanul.
However, it was worth to make the efforts as Raul now receives positives reviews. “The invention is extraordinary. Hope he goes on with bigger and better projects,” says a reader. “I’m really impressed”, wrote another websurfer.
