Jet Engines

Yep N128LR, white with a green tail and winglets. It came into BHB a few times last summer. Flies 135 out of ABE.

Lear 28 sn 001. It was the plane Neil Armstrong flew to get nearly every time to climb record in existence.

I would stop whatever I was doing just to watch that thing take off. Simply amazing.
 
I feel the need to contribute to the geekness just a little bit more. It's a common misconception the JT8D is a Turbojet. It is a very long narrow engine, which gives it that look. Its nearly identical looking to the actual turbojets on the older 707s and DC-8s. Boeing was a big "fan" (no pun intended) of the JT8D. Offhand, 737-100/200, all the 727s, later model 707s. And of course DC-9s/MD-80s. Im sure there are many more aircraft that use that engine, but it's a very strong, proven engine, and makes quite a noise. :)
 
another great plane to listen to that has this lower pitched sound is the C-5...large bypass fan on that guy.

Yeah, Sorry. But I figured i'd chime in

Engineering is rubbing off on me. Not sure if that is a good thing or not.

It's all good. You'll be a zillionaire by 35 and you'll be hiring one of us to fly around your G-VI.

Having worked as a mechanic on JT8's, I have to chime in and say that any engine that is required to be changed to fix a failed bleed valve is a piece of crap.

Hey, It takes two to fly a Gulfstream. Of course the FO will be paying me for the privelage of flying a G. So I guess you are right, I'll only be hiring one pilot. I'll start taking resumes now, to be accompanied by a $50 review fee, Checks can be made out to Justin Vroom. I'll take the green stuff too.;)
 
This is non-sequitur but you've got to get into the F1 racing circuit man.

Know of a team that would hire an entry level engineer, and get him a work visa?;)

I do have some IC engine tuning experience, if that helps.

Seriously, I would drop all aspirations of building airplanes to be an engineer for a F1 team.

Good luck...I look forward to seeing you interviewed by Windsor on Speed!!​

 
My understanding of the reason why you get the "buzzsaw" (grinding/growling) sound on the fan on engines is due to low intake airspeed and high power.

You'll notice as you climb and the speed increases, the buzzsaw sound dissapates.
