CRJ Engines

I've got a couple questions about the engines on our trusty CRJs.

Is it just me, or are the engines tilted a little bit(higher in the front)? I've noticed it alot more on CR9s, but you can see it on the 50 and 70seaters too. I've also noticed this on M88/90s. What is the purpose of the engines mounted on an angle?

Also, do the CR9s and CR7s have more powerful engines than the CRJs? I work CRJs everyday, and have worked 1 CR7 diversion, and the engines didn't look too different to my elementary eye.(didn't really get a good look, had to climb in the bin and offload all the bags for the angry diverted pax, then reload them 2 minutes later when the flight got cleared)

Thanks

Hi ColoAvs19 nice to see you on the board again, how are those biceps coming along?

Hmmm, I'm guessing the engines appear "tilted" because of the plane's ground stance and are horizontal in level flight.

Here's some info on the Bombardier CRJ

Keep'em flying

Tilted angled engine? I am not familiar with CRJ's but I can tell you that tilted engines on aircraft are common. They are tilted to offset the torque. Like a helicopter has the rotor blades to combat the torque effect, a jet engine has tilted engines to offset the effects of torque. This is why on the right engine on a B757 the engine oil sight glass is pretty accurate, whereas on the left engine, due to its tilt compensation, the readings for the engine oil are going to be full before the oil makes it to the full index mark.
