THe biggest single engined a/c
 

An idle thought. What was/is it?

DHC Otter, something Russian? For now lets stick to propellor and introduce jets as the thread flags.

Sir George Cayley

Do you mean largest wingspan as the sole measurement of size ?

Vickers Wellesley maybe?

ANT-25 was much bigger than the Wellesley.

Lockheed U2, maybe?

Gunston says the Tupolev Tu-91 was the most powerful single-engine propeller aircraft ever built and with a MTOW of 31,746lb I wonder if it was the heaviest?

Cheers.

Nope.
They just keep getting bigger! The Douglas XTB2D-1 Skypirate at 34,760 lb...?

Maybe a stretch of the thread.

Three Boeing 299Z ships were converted from surplus B-17G stock by Boeing. They were used by Allison, Curtiss-Wright, and P&W as engine testbeds. All three ships were, on occasion, flown in cruise with the four R-1820s shut down, so the only power was the single testbed engine.

Note that P&W's ship, NC5111N, was retired to the Bradley Air Museum (or New England air museum) and damaged in a tornado in the late 70s. This ship eventually was reconverted to B-17G, and became "Liberty Belle", flying from 2005-2011 for the Liberty Foundation. It was destroyed by fire after a forced landing two months ago.

The odd Lancaster used to be used for the same purpose. One was for the Mamba trials and used to spend some time on one engine.

In this picture it looks as if No1-3-4 are feathered with No 2 unfeathered for a quick start if neccessary.

Biggest single engine piston was called the Evangel; only a few built but they were bigger than an AN2.
I can only find details of a twin version, but I'm sure I read a story in an American magazine about a single engine high wing version.

Does BA flight 9 (B747) count, south east of Jakarta when they managed to restart one engine? Okay I admit they became a multi pretty quickly afterwards, but for a few minutes were a pretty big single engined aircraft!

Odd Lancaster
 

Far East Driver - Isn't your " Odd Lancaster " a Lincoln?
(For largest single Propeller driven aeroplane the Linke Hoffman R II beat the Lincoln by over 18 ft wingspan at 138+ ft and about 25 years IIRC)

Photos guys we need photos:ugh:

Whiling away the time monitoring an SC Challenge, I thought I may as well oblige!

Courtesy of henry crun: the ANT-25 1933: Wingspan: 34m (111 ft 7 in), Length: 13.9m (45 ft 7 in), Height: 5.5m (18 ft 1 in)

Powerplant: 1 × Mikulin AM-34, 560 kW (750 hp (later forced to 874 hp)) at 1,760 rpm for cruise

Power was supplied by four 252 horsepower (188 kW). Mercedes D.IVa engines, arranged in pairs, in the central fuselage driving the propeller through clutches, shafts and gearboxes.

As Haraka intimated, the Linke-Hoffman R.II was probably the largest single propeller aircraft ever built and flown

Smiling at the concept of a 5 engined a/c being classified as a single ...come on guys LOL

5 donks = 5 donks

1 donk = 1 donk :)

Sure.

The Douglas XTB2D-1 from a December 1981 Wings article....

Hence why I dispensed with the Linke monster and the Douglas XB-42 with two Allisons.

Intriguing thread :ok:

Here's a thought.

When we have solved this conundrum, how about a discussion on the worlds' smallest single engine aircraft (excluding models of course and it must have been flown by a human on board). :)

I reckon Noyade and I know what it might be.

How about defining biggest?

Reason for my question:

For Douglas XTB2D-1, the weights are:

Empty weight: 18,405 lb (8,348 kg)
Loaded weight: 28,545 lb (12,948 kg)
Max takeoff weight: 34,760 lb (15,767 kg)

What would be the best comparable weight for "biggest" single engined a/c"?

If this was not fun, please disregard.

For me, I've obviously been looking at weights, however dimensions are certainly another factor to consider. The ANT-25 has an impressive span and I'm ashamed to say I spent a considerable part of the morning looking for something bigger. :) Closest I got was the Egret...
