What they should have done is put the TFE731-40 on the Lear 45 instead of the TFE731-20... Would have given a LOT more thrust up high...pilotpair said:The 60 engine on the 45 airframe would be a heck of a combination. But that will not come to pass. Lear would lose one of it's product lines, as Gulfrstream almost did with the combination of the G- II airframe and the G-III wing combination.
It looks like they made a lot of improvements, but they are still using the TFE731-20 instead of the -40... However it appears they are using a different dash number -20BR vs. the -20AR... The BR has a high flat rating temp (104°F vs. the AR's 88°F) so it should be slightly better than what they have now... It is interesting to note on the new Lear 40 they are still using the old TFE731-20AR...Groundpounder said:Doesn't the 45XR fix alot of the hot and high problems, and allow full tanks, full seats?
the point .77 @ 450 that I saw this afternoon would also seem to argue with this statementGVFlyer said:then cruises at .73 due to winglet flutter.
