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.

This looks like a superior solution in every way compared to Valor, but it doesn't have a good enough name so I guess we'll take the Marine Widowmaker 2.0

There doesn't appear to be a general motorcycle thread on the board, so here's one.

I'm strongly considering getting a motorcycle. It's not for the cool factor, but because they seem like extremely affordable, practical commuting vehicles. The only thing that would keep me from getting one is my local climate. Anybody here ride in the desert? What's it like wearing All The Gear, All The Time in the Mojave in August? How long can one ride when it's 106 degrees out before it becomes intolerable?

I actually saw one of these on the road in the DC area once. Surreal as hell to watch in motion, but the sponson-mounted wheels for low-speed balance are apparently turbo-awkward.

Right now I'm resurrecting a Honda Cub from 35 years being stored in a barn, but once that project is done I'll probably get some small adventure or dual sport bike like the Versys X 300, CRF250L, or the CB500X

Problem with making planes without landing gear to belly-land on carrier decks covered with soft rubber is that the plane...
- Would have to be winched and taken to the elevator, catapult or placed on a wheeled cradle because it has no wheels to move around on deck.
- The plane cannot land with any stores under the wings like fuel tanks, rockets, missiles, bombs, gun pods or, as with this EA-18G Growler, delicate electronic jamming pods. Because they would be smashed upon landing.

Even using stealth fighters that keep their stores in internal bomb bays, the rubber landing method would still be insane.

- The unmanned X-47B completes its first landing aboard USS George H.W. Bush (CVN 77), July 10, 2013, off the coast of Virginia. This event marks the first time the Navy landed an unmanned aircraft aboard an aircraft carrier.

yeah it has some comical shit glued on, but the odd thing is... the rotors really stand out. A bit too thought out looking, as I can't imagine them bothering to make a swashplate, which makes me wonder if under all that crap is actually a helicopter they purchased. I would have guessed some sort of ultralight kit plane, but I think it would be too complicated for that.

the way the rotors attach seems different and I doubt this guy had a budget for any French aircraft. I think it could be a Chinese knockoff of a Schweizer / Hughes family of light helicopters. Here is an image of one the Chinese call AC310, the way the rotors attach seems very similar, and this guy already works with the Chinese to "design and build" Chinese cars. If it is, then it is probably safe to assume it really is a jumble of spare parts and not a full aircraft being visually modified. Reason being I doubt he would go through the effort to modify the typical simplified tail on these helicopters. (tail rotor at the end of a straight drive shaft instead of a two part design required to have the rotor further up the tail.)

  Huh... that's pretty fast.
Sprint Missile https://youtu.be/kvZGaMt7UgQ
The Sprint missile was part of the ABM or Anti Ballistic Missile system. The missile would carry a 20 kiloton warhead and would travel at hypersonic speeds to find and destroy an incoming enemy ICBM. Watch as the missile approaches speeds upward of Mach 10 in 5 seconds. The missile begins to glow from air friction. The ABM system became functional on October 1, 1975 for one day and was then shut down. See more about ICBMs and ABM systems in the film "Nukes In Space - The Rainbow Bombs."

https://en.wikipedia.org/wiki/Sprint_(missile) The Sprint accelerated at 100 g, reaching a speed of Mach 10 in 5 seconds. Such a high velocity at relatively low altitudes created skin temperatures up to 3400°C (6200°F), requiring an ablative shield to dissipate the heat. It was designed for close-in defense against incoming nuclear weapons. As the last line of defense it was to intercept the reentry vehicles that had not been destroyed by the Spartan, with which it was deployed.
The conical Sprint was stored in and launched from a silo. To make the launch as quick as possible, the cover was blown off the silo by explosive charges; then the missile was ejected by an explosive-driven piston. As the missile cleared the silo, the first stage fired and the missile was tilted toward its target. The first stage was exhausted after only 1.2 seconds, but produced 2,900 kN (650,000 lbf) of thrust. The second stage fired within 1 – 2 seconds of launch. Interception at an altitude of 1,500 m to 30,000 m took at most 15 seconds.
>> No. 21676 ID: a16d42
  A hypersonic two-stage, solid-fueled anti-ballistic missile, designed as a last resort short-range defense against incoming enemy nuclear warheads in their terminal phase.

It was developed as a counterpart to the long-range LIM-49 Spartan. The Sprint missile was essentially the last card on the table for any enemy nuclear warhead that evaded the initial Spartan intercepts. Because the terminal velocity of nuclear re-entry vehicles is so incredibly high (roughly 17,400 MPH / 28,000 KPH), there is little time to stop them.

In order to rapidly facilitate a launch, the silo doors housing Sprint missiles were blown away by explosive charges, after which an explosively-driven piston kicked the missile from the silo. An instant later, the first stage rocket engine ignited and burned for just 1.2 seconds, accelerating it at 100g with 650,000 pounds of thrust (294,000 kg)

This was part of the Safeguard Anti Ballistic Missile System setup in the 1970s to protect the Minuteman II ICBM field out of Grand Forks ND. Originally it was designed to defend a city, but they decided that was crazy so they scaled down the program to defend the missile fields. The system was operational for a week or so before it was deactivated because of a treaty. They built a huge nuclear hardened fire control radar, the MRS that locals called the PAR, and supposedly could detect a basketball sized object as it came over the north pole and Hudson's Bay. The 4 remote sprint launch sites were 20 or so miles away from the main radar. Crazy stuff. The feds abandoned the site and a photography crew went in to document it a few years ago. The local university, the University of North Dakota, is working to purchase the land and use it as a training space for UAVs for its aeronautical program. http://rebrn.com/re/missile-accelerates-at-g-reaching-a-speed-of-mach-in-seconds-beg-2265707/

Now that I've checked some recent developments, it turns out that there's a new system, which is a replacement of the old USSR A-135 anti-ballistic defence.

A-135 used to be a stationary, ground-set missile launch complex located all around Moscow, with radar stations positioned at the outer limits of USSR back in the day. It has the main purpose of protecting the capital from incoming nuclear missiles (a limited amount of them, that is), and at that, it uses 2-stage interception system. At longer distances it uses a large, long-ranged nuclear missile with huge thermonuclear payload designed to take out the missile with an explosion, while in shorter distances (in fact, several kilometres from the launch site) it uses short-ranged, very fast missiles to destroy them before the explosion. The maximum flight time is such missile is 12 seconds, and maximum speed is over 2 kilometres per second. Which is why it has a kinetic penetrator instead of any warhead at all.

The new A-235 system is a second attempt (after first attempt was lost in economic decline of 90-s) to replace old vehicles and expand their capability. Compared to that, more famous S-500 anti-ballistic system is a mobile platform with similar purpose, but actually has only one major component instead of several. A-135 and it's successor uses Don-2N radar station, which is functioning is fully automatic mode.
