Sukhoi 22 and Tumanski R29 engine
Now this was a thing that I could just not resist. Someone laid down a gauntlet for me. If I were able to reduce the weight of an SU-22 (about 17 tonnes) to that which would enable it to be airlifted by Chinook (10 tonnes or less) I could keep anything that I wished. The only stipulations being that I left it looking like a jet and safe to airlift. They had approached the owners of an SU-22 in the UK only to be told how long it would take and that it was impossible without shipping all their tooling over and getting a specialist guy from Russia or the Czech Republic. The trouble was they wanted it doing and doing now.
So I said urm, yes ill do it........... DOH!!!
started by de-paneling and surveying the airframe to determine
its condition, completeness, and how it was assembled. The
aircraft turned out to be 100% complete. I did try go get
permission to run it prior to dismantling itbut to no avail.
So I looked at what components would best reduce the weight,
decided what needed to be removed roughly roughly and made
my mind up what to do. Next came the draining of the fuel
and oil, the next was the task to depressurize the oleos
and find any other systems that were still pressurized such
as the fire suppression system, accumulators, flying control
and general services hydraulic systems etc and deal with
them. The next task was the seat, this I was not sure about
so I bought a K36 seat manual from the Ukraine, made some
safety pins and lifted it out.
