The Ongoing Mystery Aircraft Thread Part Deux.

This one is post-war (even 1960s)
Again I would like to learn what make engine was fitted, since I donot know.
 
This is a Noorduyn Norseman which has been modified with a different landing gear strut configuration and what appears to be a larger V.Stabilizer. It also appears to have the panoramic window modification. Norseman Mk.I - 420HP Wright, MK.II - 420HP Wright, MK.III - 450HP P&W R-985, MK.IV - 550HP P&W R-1340, MK.VI - 600HP P&W R-1340, MK.V (Built after the Mk.VI - "V" designation was saved for 'victory' after WWII - built by Canadian Car & Foundry for civilian use) - also used the 600HP P&W R-1340. There was also one metallized prototype MK.VII, but performance suffered due to the extra weight. Project was dropped. Hard to tell which Mark this one is/was, except I'm pretty sure it's not a Mk.VI as they used 2 bladed props.
Looking at the picture I also noticed that the lift struts seem to be beefed up as compared to the standard struts of all the Norseman I've seen.
 
DHC2Pilot can be on the right track with the Norseman connection since it is sometimes rumored that is was built from (or influenced by) the famous Dutch Canadian.
However, this one comes from a country, not that far away (but still in Asia)
and the manufacturer still build airplanes.
The jury will accept two designations.
 
Ok, now I feel dumb....LOL. If that's not a Norseman, then they had one sitting in the shop for taking measurements from when they designed it.
 
DHC2Pilot, no reason to feel dumb, to the contrary:icon_lol:
You may be absolutely correct in that it is (was) a Norseman However, I never was able to get confirmation on that and that is why I still wonder about the engine (P&W?, Alvis?, Russian?).
The aircraft is the Hindustan HCP-125 a.k.a. the L.A.S. for Logistic Air Support. First flown in September 1960 and developed under leadership of Dr.
C.N.Ghatage and intended as light transport (8-10 seat), flying ambulance etc. One story goes is that it may have been a modified Norseman with a 3-bladed prop, additional cabin windows, curved l/e on the vertical tail, a modified u/c attachment with small stubs supporting the main wheels (see photo) rather than the more standard fuselage gear legs. If there is a Norseman connection I would opt for the 600hp P&W R-1340 as engine. Although I never found out what engine was used, reports indicated that is was a 600hp unit. Btw, did the Indian AF not operate the Norseman?

So..... now I stay up all night to see all the info on this aircraft coming in.



Open House please
 
If in fact it was a modified Norseman, it'd be interesting to learn what they were trying to accomplish by increasing the size of the V.Stab - the Norseman had plenty of rudder authority - either on wheels or floats. My father owned a Norseman on floats years ago in Int'l Falls, Minnesota and said it flew nicely, albeit not as easy on the controls as a Beaver, and couldn't match the Beaver's or Otters STOL capability. I guess this just goes to show that there's always someone that has to tinker with things, good enough or not. :)
 
Interesting mysteries Walter. We don't get too many from India or Vietnam!

Here is one that doesn't hail from Asia...
 
The illegitimate offspring of a Spartan Executive and a Couzinet? Do we possibly owe credit to our French friends for this curious design? The cowling hints of Russia though. Things that make you go "hmmmmmm."
 
And this one certainly doesn't suffer from an excess of vertical stabilization.... Think it's another Aerofiles special.

BTW, Wout, the HCP-25 seems to have only the briefest mention in any of my tomes. However, the earlier HT-10 used a P&W R-1830 - maybe it is conceivable they used the same unit for the later aircraft ? Dashed economical, these Indian wallahs, what ?

Sooooo close... It's the Spartan 7X Executive:

7X Executive (Standard Seven) 1935 = 4pClwM rg; 285hp Jacobs L-5; span: 39'0" length: 26'8" v: 160/150/45 range: 800. Small tail, long dorsal fin. POP: 1 prototype of the 7 series; ff: 2 (?>3)/19/35 [X/NC13984] c/n 0. Reportedly delivered to Mexico.
 
Reminds me of this.....

Blargh.....I was looking at the 7W and completely neglected to look at the 7X. That cowling had me thinking more and more towards Russia. Chalk that one up to tunnel vision.

I posted that particular photo for exactly that reason. Needed a hint of ambiguity there to try to throw you all off.



Edit: Lefty, you are right of course on the Vultee. How about posting a new one? Ferry seems to be away.

Just got home from work, but of course Lefty is right about the Vultee. :)

P.s. Mike: Aeroplane, January 2010, page 35. :icon_lol:
 
I had this photo in my queue. Might as well post it now.

The Vultee sure is a sleek floater. Would like to see a FS version (doubtful).
 
Ahhhh, floaters.... you wouldn't expect me to deviate from this theme, now, would you ?

I could bring the thread to a halt with this one....
