"Do you have any information on the 1951 flight testing of TV-2s on the Tu-4?"
The TV-2 at that time had, as per its trials:
5163 shp (taking off mode)
3740 shp (cruise mode)
dry weight (whole assembly) 1700 kg
The Tu-4 performance with TV-2 could be improved at 15-20% only, which
wasn't enough, so they stopped further works.
"Was the TV-4 another Isotov design?"
Sergei P. Izotov (1917-1983) - chief designer of air-engines.
A disciple and first substitute V.Ya.Klimov’s……With 1962 more than 20
years stayed at the head of "V.Ya. Klimov" factory .
As per my opinion, it is about the same engine. :-\
