Lord, love a Leduc!
Designed by René Leduc in 1938, it was built at the Breguet Aviation factory after a protracted, semi-secret construction phase kept at arm's length from German occupation authorities, and was finally completed in 1947. The aircraft featured a double-walled fuselage, with the pilot controlling the aircraft from within the inner shell. The circular gap between this and the outer, cylindrical shell provided the inlet for the ramjet.

Testing: It could not take off unassisted (ramjets cannot produce thrust at zero airspeed and thus cannot move an aircraft from a standstill) and was therefore intended to be carried aloft by a Sud-Est Languedoc mothership and released at altitude. Following test flights of the Languedoc/0.10 composite, independent unpowered gliding tests began in October 1947. After three such flights, the first powered flight was made on 21 April 1949 over Toulouse. Released in a shallow dive at an altitude of 3,050 m (10,010 ft), the engine was tested at half power for twelve minutes, propelling the aircraft to 680 km/h (420 mph).

In subsequent tests, the 0.10 reached a top speed of Mach 0.85 and demonstrated the viability of the ramjet as an aviation powerplant, with a rate of climb of 40 m/s (7,900 ft/min) to 11,000 metres (36,000 ft), exceeding that of the best jet fighters of the time.

Of the two 0.10s originally built, one was destroyed in a crash in 1951 and the other severely damaged in another crash the following year. Both pilots survived with serious injuries. https://en.wikipedia.org/wiki/Leduc_0.10

- French Leduc 0.10 1949 ramjet interceptor carried by a Sud-Est Languedoc mothership.
A piloted ramjet, first flown in powered flight on April 21st 1949. As a ramjet needs forward speed to operate, it was carried aloft by a Sud-Est Languedoc mothership and released at altitude. In flight testing, it reached speeds as high as M=.85. On display in the Musee de l'Air et de l'Espace. Of the two names on the aircraft, Rene Lorin was the inventor of the ramjet and Jean Villey published the detailed theory of the ramjet. http://www.airliners.net/photo/Leduc-010/1492573/L/

The Hiller YH-32 Hornet (company designation HJ-1) was an American ultralight helicopter built by Hiller Aircraft in the early 1950s. It was a small and unique design because it was powered by two Hiller 8RJ2B ramjet engines mounted on the rotor blade tips which weigh 13lbs each and deliver an equivalent of 45 h.p. for a total of 90 h.p. Versions of the HJ-1 Hornet were built for the United States Army and the United States Navy in the early 1950s. https://en.wikipedia.org/wiki/Hiller_YH-32_Hornet
- Displayed in Museum of Flight in Seattle. This is one of 12 YH-32s acquired by the Army for evaluation in 1955.

What the shit? Looks like a couple of V1 buzz bomb engines.

> How ever even this stunning aircraft was out performed by the new jets of 1944/45 and like the Soviets in an attempt to prolong the live of the "Mustang" as a front-line fighter a pair of Ford PJ-31-1 pulsejets were fitted on to the under side of the wings. The results were similar to the Soviet experiments on piston engined aircraft with added pulsejets, an increase in top speed when in use, but with excessive fuel consumption and high drag when not, the idea was dropped soon after the tests.

Indeed it is.

  There's also the Motorjet (also conceptualized by Rene Lorin) which is where you use a piston engine to run the compressors on a jet engine. Only the Italians and Russians really explored the concept, the Italians with the Campini C.1 aircraft (one of the first jets) and the Russians with the MiG-13, a prop fighter developed as a crash response to the Me 262, which used a turbojet as a booster and was never accepted for service due to being obsolete (by the time they figured out the engine stuff the MiG-9 existed) and having a number of design flaws.

Here is a good article summarizing the status of the Bell V-280 Valor Tiltrotor, one of (ann my personal favorite) the candidates for the Army’s Joint Future Vertical Lift program. http://nationalinterest.org/blog/the-buzz/the-us-militarys-next-super-stealth-weapon-not-what-you-19090?page=2

No mid wing gearbox: http://www.military.com/daily-news/2016/01/15/bell-touts-future-army-helicopter-design-v280-is-not-a-v22.html

As a 3rd generation tiltrotor, It is also supposed to have better Hot / High / Heavy characteristics than the V-22

One of the discussed versions is to be a slightly modified airframe for an attack version. Once the proof of concept is done and they have won the contract, I think they should instead use the front half of modified AH-1Z airframe, modified to carry a similar useful load to the Apache. The Cobra has a useful load of 5,764, Apache has around 9000 Pounds useful load, and the V-280 is currently touted to have a useful load of 1200.

Tanks!
The Medium Tank M2 was a United States Army tank that was first produced in 1939 by the Rock Island Arsenal, just prior to the commencement of the war in Europe. Production was 18 M2 tanks, and 94 slightly improved M2A1 tanks, for a total figure of 112. Events in Western Europe and on the Eastern Front rapidly demonstrated that the M2 was obsolete, and it was never used overseas in combat; it was used for training purposes throughout the war.

The M2's unique features included an unusually large number of machine guns, bullet deflector plates, and sloped armor on the hull front (glacis plate). The main armament was a 37 mm (1.5 in) gun, with 32 mm (1.3 in) armor; the M2A1 had a 51 mm (2.0 in) gun mantlet. The features of the M2 series development, both good and bad, provided many lessons for U.S. tank designers that were later applied with great success in the M3 Lee, M4 Sherman and many other armored fighting vehicles. http://en.wikipedia.org/wiki/M2_Medium_Tank

Armed with 1× 37 mm Gun M3 and 7× (maximum 9) .30-06 Browning M1919 machine guns.

I have read the Sheridan described as a bunker-blaster demolition light tank. Her 152mm gun fired conventional ammunition and the MGM-51 Shillelagh guided anti-tank missile. Armed with low velocity HEAT rounds that were good for blowing up bunkers & buildings without over-penetrating like the high velocity guns on the MBTs did, and also shooting big canister antipersonnel rounds spewing out flechettes.

It's probably a leaky oil pan or valve cover gasket.
The gaskets get old and 'dry out', letting oil past. The oil then blows all around the engine bay, getting on the exhaust (making smoke) and trapping dirt leaving everything it touches fuzzy with dirt.

Crawl under your car, take pics and post them.

However it was derived from the failed 1977 Cheetah project, a attempt to compete with the HMMWV and XR311. (and by extension similar NATO-market vehicles like the Iltis)

And it was mainly introduced in a attempt to make lemonade from lemons, since Lamborghini went bankrupt in 1978.

I'm sure I've posted jeep comeback stories here before, but here's the latest rumour from warhistoryonline:

https://www.warhistoryonline.com/featured/u-s-military-may-bring-back-jeep.html

With the JLTV costing the expensive side of $400K per unit, it makes sense to have a cheap utility vehicle for rear echelon duties, so would a militarised Jeep Wrangler fit the bill?

that stow able weapons platform seems a bit awkward. Would be unpleasant if someone accidentally hit the switch with a squad crammed in the back. Still, it is interesting to see the effort they go through to make this fit as easily into an aircraft as possible, not a whole lot of vehicle will fit inside the CH-47. (although they have carried sling loaded humvees before) Not quite as tiny as the Boeing Phantom Badger tactical golfcart that will fit inside a V-22, barely.

I think outfitting the crew with 7.62 neato LMG and just punching some roof hatches would make way more sense.

>Boeing Phantom Badger tactical golfcart that will fit inside a V-22, barely.
>lets build 200 new transport aircraft!
>oh no we made them too small!
>lets build 5000 super small vehicles just on the off-chance that they have to be transported by our small aircraft!
Never understood this line of thinking, it puts the people who have to ride those vehicles into danger and it's probably more expensive in the long run. Why don't they just build 200 of bigger aircraft to fit the vehicles currently in use, then they don't need brand new tiny vehicles and can save money by using the old vehicles.

It seems like a backwards way of thinking (the vehicle being there to serve the transport aircraft instead of the other way around).

And while we're on the subject...
JLTV thread!
https://oshkoshdefense.com/jltv/
To me, this vehicle has a certain resemblance to the International Navistar MXT-MV Husky used by the British army, in that it follows a pick-up truck layout with a MRAP body. Which rather makes me wonder why the MXT wasn't a contender for the JLTV contract?
>> No. 21530 ID: ad2b13
It suffers from the same problem all multiroles suffer, which is lack of efficiency. And as the other thread is being discussed, it also leaves a gap in low-intensity general work that makes every military functional.

Other than that it's an ok vehicle, considering it replaces humvees juryrigged with extra armor.

>Which rather makes me wonder why the MXT wasn't a contender for the JLTV contract?
Other way around, I think the British are going to buy the JLTV.
