Oddball, Experimental, or One-off

[red750]

The Vertol VZ-2 (or Model 76) is a research aircraft built in the United States in 1957 to investigate the tiltwing approach to vertical take-off and landing.

 

The aircraft had a fuselage of tubular framework (originally uncovered) and accommodation for its pilot in a helicopter-like bubble canopy. The T-tail incorporated small ducted fans to act as thrusters for greater control at low speeds.

 

Ground tests began in April 1957 and on 13 August, the VZ-2 took off for the first time in hover mode only. On 23 July 1958, the aircraft made its first full transition from vertical flight to horizontal flight. By the time the test program ended in 1965, the VZ-2 had made some 450 flights, including 34 full transitions. The aircraft has been preserved by the National Air and Space Museum in storage at the Paul E. Garber Preservation, Restoration, and Storage Facility. Only the one prototype was produced.

The Margański & Mysłowski EM-10 Bielik (English: white-tailed eagle) is a low-cost Polish military training aircraft prototype, built by Margański & Mysłowski Zakłady Lotnicze, and first flown on 4 June 2003. The single-engine aircraft has a composite (mostly carbon fibre) fuselage with a light-alloy aft section, and the pressurized cockpit is fitted with ejection seats.

Can I register one as 19-?

Sure, as long as you built it. 😉

[facthunter]

Maybe in Libya.?  Nev

[facthunter]

Stall speed and wing load  AUW and a few other things might get in the Way.  Nev

[red750]

Wingspan: 6.60 m (21 ft 8 in)
Height: 2.50 m (8 ft 2 in)
Wing area: 11.90 m2 (128.1 sq ft)
Aspect ratio: 3.7
Empty weight: 1,700 kg (3,748 lb)
Max takeoff weight: 2,500 kg (5,512 lb)
Fuel capacity: 850 kg (1,870 lb)
Powerplant: 1 × General Electric CJ610-6 turbojet, 13.5 kN (3,000 lbf) thrust prototype; production aircraft 12.75 to 17.65 kN (2,870 to 3,970 lbf) turbojet / turbofan
Performance

Maximum speed: 1,100 km/h (680 mph, 590 kn)
Maximum speed: Mach 0.9
Stall speed: 165 km/h (103 mph, 89 kn)

 

A bit heavy, and stall speed is a tad high.

[facthunter]

Yeah Stall speed is a normal U/L's cruise speed. Nev

In defence aircraft spending terms, "low cost" to produce, means a figure of around $20M to $40M. But I'm sure Martys got that amount hanging around the house in loose change. 😄

Fuel costs could be an issue. We had to fill up today, we're planning to be in Brisbane over Easter and Shark bay in mid May. Too much travel to risk running short.

 

 

This should carry us over the present crisis.

Very pretty aircraft.

 

The belly air inlet, directly behind the nose wheel, (kicking up stuff) look like  a high risk of stuff entering the engine???😈

Lucky you've got a gold mine to finance your fuel requirements, Moneybox! Most of us are sitting here, watching our limited funds get savaged by oil companies, and oil futures traders!

I didn't buy that fuel, it was on the monitor when Mrs M went up to the counter to pay for her $100 worth. She was listening to them bitching about somebody taking $480 worth of fuel and creating a shortage for everybody else. If somebody is going to take $22,000 worth in one swipe what difference would it make for an individual to take $480 worth?

[facthunter]

It ALL adds up doesn't it? The extra is Multiples of normal usage rates. Land of the fair go? Ha HA. Nev

[onetrack]

Well, if they were refuelling a Kenworth pulling a road train, $480 worth of fuel would barely move the fuel gauge.

I just got 285 litres for 750 dollars.

Imagine a large mine site at the moment. They burn millions of lts of diesel a week.

This problem is guaranteed to speed up the transition to electric trucks. Fortescue are spending $4 billion with Liebherr on 360 fully autonomous electric dump trucks. Quite a few already in service, & a lot of diesel tractor units are being retrofitted with battery electric motors. BHP & Rio Tinto are trialling Caterpillar electric haul trucks in the Pilbara. Janus Electric started the first trials from Sydney to Melbourne 2 or 3 years ago. The conversion from diesel to electric is cheaper than a diesel overhaul. They have done 25 so far. There are over 200,000 electric long haul trucks in China

Electric trucks outsold diesel in China for the first time.

 How is the power generated to supply all these environmentally friendly Australian mining vehicles?

exactly.  if they want to be green and run large electric vehicles we need nuclear power. there is nothing else that can supply enough clean energy.

[red750]

Possibly through solar farms like this one, with approximately 61,000 solar panels covering 73 hectares.

 

 

However, this topic is for aircraft which were experimental, one off's which never made it into mass production. There is a topic on Social Australia for electric vehicles.

The Sun is the Best form of Nuclear energy and Its Free. No one can have a monopoly on it, nor does it add any Heat energy to the total equation.  It's very much Part of the future.  You can concentrate it to get super high temperatures . Nev

Good luck charging a mining fleet or a fleet of trucks with solar.

[facthunter]

So you think a Nuclear power Plant would be appropriate for that Purpose?  Nev
