The Yak55 aircraft was originally designed to be charged from
a ground bottle for each start. They did incorporate a "Pop Off Valve".
The air compressors on the engines were not connected to the air start
system. Therefore they did not have the water trap, the cooling shroud
etc.
When they came to the U.S. people connected the compressor to
the system in various ways. When we did it, we usually installed a
Yak-52 type system including the long metal pipe with a loop for
cooling, the water trap, a check valve and a pressure gage. At that time
the original Russian parts were readily available so we used them.
The 1996 aircraft were probably part of the 7 new aircraft
that Tom Klassen and I imported without engines directly from the
factory. As I remember Tom assembled 5 aircraft in St Louis and Rob
Porter in North Carolina assembled 2 aircraft. We imported
several used aircraft and a few new old stock aircraft through our
facility in Vermont and modified them to be similar to Yak-52 air
systems. We also modified the straight 55's we imported to use hydraulic
brake systems instead of the original mechanical system.
