Hi all,

Piper PA-9 :high wing military liaison aircraft,project only.
Piper PA-10 :design similar to Thrope Skyscooter,project only.
Piper PA-37 :projected pressurized Twin Comanche,not built.
Lo Presti-Piper Swiftfury :was developed from Globe Swift,it had a new
Flush-riveted wing skins, a sliding cockpit canopy and a 425
hp Allison 250 turboprop engine.
Piper Twin Stinson :was developed from Stinson design as twin engined
four seat low wing twin of tube/fabric construction
with twin tail fins,fixed tricycle u/c and two 125 hp
Lycoming O-290-D engines.

I would like to know more about this one, please... Is this a twin-fuselage like the Wagner Twin-Cub? or else a simple Stinson with "just" 2 engines and 2 fins (but a single fuselage)?
;D
 
Dear Tophe,

it was a simple Stinson fitted with two engines.also see:

Hi all,

the Piper Aircraft Corporation build a long series of light aircraft, but in this list are some gaps. Do you know anything about the Piper P.A.7 and 8; P.A.13; P.A.26 and 27; P.A.37; P.A.39; P.A.41; P.A.43;P.A.45...47...49...?
Please if you have with pics, drawing and technical data.

You might look for copies of 'Standard Catalog of Piper Single Engined Aircraft', and 'Standard Catalog of Piper Twin Engined Aircraft'

Piper Aircraft by Roger Peperell
[190] $124.99



The definitive historical guide to Piper aircraft.

Roger Peperell, Official Historian of the New Piper Aircraft Corporation, brings you a fully revised edition of Piper Aircraft: The Development and History of Piper Designs.

Piper Aircraft is an accumulation of four decades of investigation and interviews. It is the most detailed source covering the development and history of one of the most well known aircraft manufacturers in the world.

The book examines prototypes, production histories, specification details and performance data of Piper’s aircraft from its forerunners, the Chummy and Taylor Cub, to the current, state-of-the-art line-up. Also featured are aircraft that were designed but never built, and aircraft considered for acquisition.

Piper Aircraft features 640 color pages 1,700 illustrations including engines, panels, interiors, adverts, logos, newspaper cuttings, three-view drawings and artist impressions.

the PA-39 was a development of the PA-30 Twin Commanche.

Specifically it is nothing more than a PA-30 TwinCo with counter-rotating propellers (that is, each propeller turns in a different direction) for enhanced engine-out performance. It may sound simple but try running your car's engine backwards - the -39 requires mirrored camshafts, piston domes etc. Though it did enter series production (you might be able to find one or two at your local flight line) it was soon superseded by the Seneca and Seminole (both of which, starting from the Seneca III and from the first model Seminole, counter-rotating props)

Someone already mentioned the Skycycle (built from a surplus F4U droptank, BTW - yes, really!). The PA-7 Sky Coupe was an experimental four-seat light aircraft for the post-war market:

piper_pa-7.jpg


Never saw production, BTW

The Piper PA-26 appears to be an alternate designation for the PA-28-161 Warrior, I'm not sure on that. The PA-27 likewise seems to be a variant of the PA-23 Aztec, possibly with counter-rotating props like the -39 (I do distinctly remember there being quite a few counter-rotating Aztecs around).

The PA-41 is the Cheyenne II turboprop, a fairly common aircraft actually.

The others I'm not familiar with. Keep in mind that Piper did a few experimental trainer bids here and there, and I'm betting they fill in the missing numbers. It also appears that the PA-13 designation was deliberately skipped (hey, we pilots are pretty superstitious you know :p )
 
Actually, the deal with the PA-39 is pretty simple. It was just an engine & prop change. After the PA-39 came out, PA-30 owners could get the left hand rotation engine & prop conversion kit & install it in place of the right engine.

That's true, but my point being...well, any A&P will tell you that an engine swap isn't exactly simple :p

The engine is the same, but there are significant changes to it to essentially make it run backwards. Like I said, mirrored camshafts and piston domes to make it go in the opposite direction etc. There might even be basic block changes. What really makes it not so simple is the cost of doing all this stuff (remember, airplane parts are significantly more expensive than automotive parts) which is why it took so long for engine manufacturers to even be bothered doing it.
 
Yes, AS an A & P, an engine swap isn't necessarily simple, but I think you're making a point of something different. The engine is built differently, that's why it's designated an LIO-320-something rather than an IO-320. Otherwise, as I understand, since I've only done standard engines on TCs, it's still just an engine change.

I wasn't trying to make a point that it's different, but yeah, you're right, I was just not communicating it clearly. It is an LIO-320, the "L" standing for left-rotating, naturally.
 
I've never seen Aztecs (or Apaches) designated anything other than PA-23! Wonder what the changes were.

Hi,

the PA-9 was a project for high wing military liaison aircraft and the
PA-10 was a project for low wing two seat aircraft,design similar to
Thorp Sky Skooter.Also the PA-37 was a pressurized version of Twin
Comanche,but not built.
Source; Airlife ; General Aviation,first edition
 
  • A few details and corrections here:
    • PA-21 was given inhouse to the sole Baumann 250 Brigadier after it was purchased by Piper.
    • PA-26 was to be a high-powered version of the PA-24 Comanche but it wasn't built.
    • PA-27 was initially allocated to the Aztec, but then it was decided to use PA-23 sub-types instead.
    • PA-29 was the Papoose, an experimental prototype built in 1956.
    • PA-35 was the Pocono, the largest Piper built; single prototype was sold to PZL in Poland.
    • PA-37 was to be a twin-engined version of the PA-33 Pressurized Comanche prototype, but it was not built.
    • PA-41 is NOT the Cheyenne "II", that's the PA-42... It was a Pressurized Aztec prototype.
    • PA-43 was to be a piston-engined variant of the PA-42 Cheyenne, but it was not built.
    • PA-47 was recently allocated to the PiperJet.
    • PA-49, 51 to 59 were not allocated.
    • PA-60 was allocated to Ted Smith's Aerostar after being purchased by Piper.
    • No PA- number seems to have been given to the new PiperSport (= Czech Sport Aircraft SportCruiser).

    I'm preparing a complete recap on all Piper designations, so stay tuned!
 
Though not unknown, strictly speaking, a rare model anyway: the Piper PA-30 Twin Comanche under evaluation at NASA in 1967:

But there was a 3 engined Cherokee Six that led to the Seneca, IIRC it had to 180 hp Lycomings on the wings.

I'll see if I can find it. It's mentioned on Wikipedia under both entries for the PA-32 & PA-34 & was the Cherokee Six - 3M, IIRC.

Sorry my dear Jos,


that's the best of I could,but I will send the book to my dear Skyblazer,may be he will
find away,as I think.

Sure enough did, hesham... thanks for your trust and for the book, too! However, of course, I cannot improve on the center part that couldn't be scanned properly by the author of the PDF file because of the book's thickness (and probably some understandable reluctance to breaking its spine!).

Brilliant gentlemen, and thanks. You got a happy little chappie here downunder in Australia
