Good skills, Skytrain!

Yes, this is part of an aircraft (one that only concerns itself with the troposphere!).

Looking at

an engine?
Mmmm, not sure quite how to answer that... :8


If it's not on a pylon then by definition it must be integral
Mmmm, not quite sure what I think about that, either, in this context!

Not being obstructive - you'll understand my answers when things slot into place. ;)

Harley Quinn 7th Feb 2012 19:23

I did toy with this idea yesterday. Spaceship One

TheiC 7th Feb 2012 19:29

Sorry, Harley, you're thinking along the wrong lines there.

I'll try to answer Skytrain a little better:

Part of the image shows part of an engine. An engineer would tell you that the whole thing is not an engine.

sycamore 7th Feb 2012 19:35

Astazou to you tooo.... off a Wetdream or a Gazelle...OH if correct...

TheiC 7th Feb 2012 19:48

Gesundheit!

Sycamore has it... :ok:

...the intake and reduction gearbox on an Astazou (on a Jetstream, as it happens).

You can see one in situ about half-way down this page of smashing photos: Latest News

Open House is declared.

Harley Quinn 7th Feb 2012 19:57

OK, I'm struggling to reconcile the sharply swept fairing centre left of the challenge, could you show the uncropped image please?

TheiC 7th Feb 2012 20:17

This should help:

I didn't get to know the aircraft well enough to find out the purpose of the fairing; thinking about it, it probably carries the harness for the propeller deicing. There's one on each engine in the one o'clock position (viewed from the rear).

Harley Quinn 7th Feb 2012 20:19

Brilliant, thank you, I can see it is the reduction gearbox now.

Harley Quinn 8th Feb 2012 18:57

Is this the cooling intake for a de Havilland inverted engine or an outlet for an exhaust?

Noyade 8th Feb 2012 19:14

Evening Harley.

It's the outlet for a ducted fan.
Japanese motor-glider.

(Found it while looking for Ken's motor-glider on SC)

Harley Quinn 8th Feb 2012 19:41

Thought that one was supposed to be Argentinian?

Noyade 8th Feb 2012 19:45

I'm was searching for motor-gliders in general.


Thought that one was supposed to be Argentinian?
Yes, if you find it, let me know.... :)

Mine above is Japanese.

Harley Quinn 8th Feb 2012 20:22

Found a side view that might match up; Nippi NP100A?

Noyade 8th Feb 2012 20:29

That's the one Harley. :ok:

Your control.

But its the best I can come up with.

I like it! :ok:

Good shooting, the I153DM with two gasoline fuelled ramjets under the wings.

Looks like the Adam A.700 AdamJet?

That's the one Ken. :ok:

Karlark 9th Feb 2012 21:15

Embraer Phenom 300?

skytrain10 9th Feb 2012 21:57

The Phenom it is Karl:ok: This one is actually the 100 series.

Karlark 9th Feb 2012 22:20

Thanks Ken. Here is the next challenge:

Noyade 10th Feb 2012 04:06

G'day Karlark. On a pylon, on a wing? Russian?

Karlark 10th Feb 2012 12:00

'evening Noyade.

Yes, 2X pylon mounted on the wings. Not Russian, though.

Edit: think business aircraft. :)

SincoTC 10th Feb 2012 12:29

Morning Karlark,

Lunchtime swoop from me too!

Avtek 400 ??

Open House if correct please as I'm back to work too :)

Karlark 10th Feb 2012 12:45

You have it correct TC :ok:. The prototype Avtec 400.

Update of Engine Inlet-Exhaust Challenge List 09 Feb 2012
 
The Engine Inlet-Exhaust List has been updated up to and including 09 Feb 2012.
Mel

TheiC 10th Feb 2012 17:52

How about:

http://i1113.photobucket.com/albums/...eb20124_hf.jpg

Same cautions apply as did to my previous challenge here!

Harley Quinn 11th Feb 2012 15:33

Seeing a small turbojet or loww bypass turbofan here. The curvature of the intake lip and its lack of depth before the blades makes me think its a fairly low speed aircraft, possibly even rotary wing, but I'm not sure if that white blob is a wing tip in about the 11 o'clock position. Did wonder if it was mounted in the wing but inclined to think its pylon mounted.
Small late 20th century biz jet

TheiC 11th Feb 2012 16:07

Hello Harley,

I'll break your hypotheses down, if I may...
  1. a small turbojet or loww bypass turbofan here
  2. its a fairly low speed aircraft
  3. possibly even rotary wing
  4. that white blob is a wing tip in about the 11 o'clock position
  5. inclined to think its pylon mounted
  6. Small late 20th century biz jet
One of your hypotheses is correct... Would you like to know which one or do you prefer a mystery?

Harley Quinn 11th Feb 2012 16:13

I'm not a masochist so yes please.

TheiC 11th Feb 2012 16:17

By all means.

Number 2 is correct.

Don't forget the word of caution!!!

Harley Quinn 11th Feb 2012 16:24

So, it's unequivocally not:


a small turbojet or low bypass turbofan
rotary wing
a wing tip in about the 11 o'clock position
pylon mounted
Small biz jet

TheiC 11th Feb 2012 16:29

Unequivocally, as you say...

Lightning Mate 11th Feb 2012 17:06


Update of Engine Inlet-Exhaust Challenge List 09 Feb 2012

Would anyone on this thread care to thank Mel......................?????

TheiC 11th Feb 2012 17:08

I did so on another thread, but am very happy to do so here as well; hope not to be considered rude for not including thanks in my first post after his update...

Thanks Mel! :ok:
