Back in 2016, 2 years before I started working on my jetpack, Evgeny Flex, my fellow countryman from Vladivostok, presented to the world his daring project with a reverse swept wing.
I wrote and called Eugene, consulted with him about micro-turbojet engines, we discussed options for possible cooperation. It's too late to write about Eugene and his work, but I still want to tell you a little about this man and his work on creating a jet wing.
Jetwing "IKAR" - 1st VTOL turbo jetpack. Design. Part 1.
Engine: 2x turbofan with RDK. DIY
the Thrust: 2000+ N (~ 200kg)
Flight time: 35min max
Wingspan 1.6m
«Right next to it is an improvised ground multi-storey house under construction ... In testing time, all construction stops - all interesting)
on the lower slide just land, scorched and melted reactive a jet of hot gases - it becomes like a hard polished quartz - this is the result of a short operation of the engines "at idle" from a height of 80 cm. " (Hereinafter, the captions to the photos are taken from Eugene's instagram)
Turbojet engine
Evgeny was developing his turbojet engine
Turbofan jet engine (TVRD) - turbojet engine with a bypass ratio m = 2-10. Here the low-pressure compressor is converted into a fan, which differs from the compressor in a smaller number of stages and a large diameter, and the hot jet is practically not mixed with the cold one. Usually used in civil aviation, the engine has a longer assigned resource and low specific fuel consumption at subsonic speeds.
We are testing the hypothesis of applicability of a hybrid gearless circuit based on a turbojet engine of our own design.
