OTC The replica 262's should have better rivets, at least!
I've been following the progress of the Snyder (Stormbird) replica project for a while. Here's some info about the new engine setup:
'A modern turbine engine, the GE J-85,_was chosen to power the replicas. This engine was designed in the 1960s for the military and_ powered such planes as the F-5 and T-38. A civilian version powered the original Lear Jet.
_
The Jumo engine produced about 1800 pounds of thrust. The J85 produces about 2850 pounds of thrust on 40% less fuel. This much thrust should allow the replica Me 262 to reach 600mph, but since the airframe is not designed for those speeds, its placard top speed is 500mph.' (speaking of Vne!)
