Sikorsky X2 Helicopter Tested, Even Cooler than Expected

Jesus Diaz — Wed, 03 Sep 2008 08:15:00 EDT

Sikorsky, makers of the Blackhawk and other sleek helicopters, have successfully tested their X2 Technology Demonstrator, a prototype designed to showcase new propulsion systems that will allow their helicopters to fly at twice the speed of conventional ones. And it looks sci-fi pretty too, even more so from the front:

Sikorsky Chief Test Pilot Kevin Bredenbeck maneuvered the prototype for 30 minutes in a few basic tasks: hover, forward flight and hover turn. The project is coming slowly into final shape but when finished, it will be able to cruise easily at 250 knots while maintaining the same features of traditional helicopters, like low speed handling, hovering, and autorotation.

World's Smallest UAV Weighs 10 Grams, Flaps Like a Bird

AreoVironment is building the world's smallest UAV, called the Nano Air Vehicle, that has moving wings instead of a propeller or engine. DARPA has given the company $636,000 and six months to demonstrate an ultra-small UAV that will be under three inches long and under 10 grams.

The concept for the project came about through a $1.7 million "Phase One" brainstorming contract. Apparently unaware of the existence of birds, DARPA decided that this innovative and classy new idea was worth pushing through to development and handed over the second wad of cash this week. The Nano Air Vehicle is part of an apparent trend toward smaller and smaller UAVs, following AreoVironment's 80 gram, six inch Black Widow and Prox Dynamics' four inch, 20 gram Black Hornet (which, thanks to the less literal-minded people at PD, does not fly like an actual insect).

Japan's Kizuna Satellite to Beam Souped Up Internet Connection Back Home

Japan is launching the Kizuna satellite, which will bring high-speed internet access to Japan's remote territories and neighboring countries, as well as providing continuous networking in case of emergency. The $342 million project, spearheaded by Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency (JAXA), is expected to culminate in internet connections reaching speeds of 1.2Gbps, dwarfing current ADSL connections that typically allow data transfer to occur at below 8 Mbps. Users will need to install an antenna to be able to receive a signal, but for those speeds, I'd be willing to trade in a pound of my very own flesh.

Kizuna is expected to go live in July following a setup process once it is in position, but a speed boost is not the only aim of the game. Having a satellite in space means natural disasters on Earth are not going to have any ramifications on the country's connectivity, which can be imperative in disaster zones. If all should go well, expect such an infrastructure to hit the mainstream. Does that mean everyone will have a 1.2Gbps connection? Will outages become a thing of the past? Does Simba eventually become a good leader? The answers come in July, when the service rolls out. [JAXA via Yahoo News; AP]

NASA Drops $19 Million on Toilet, Doesn't Let Russians Use It

Tension is bound to flare over the $19 million toilet NASA purchased from Russian aerospace firm RCS Energia, as only half of the International Space Station will enjoy the upgrade—the American side. The toilet justifies its steep price by being able to recycle urine as drinkable water, Waterworld-style.

The Russian half of the station is stuck with the old latrine. They'll have to continue to load up one of their unmanned cargo vessels with boxes of their leftovers and send it to burn up in the atmosphere, which is pretty much the equivalent of flushing right now in space.

The new toilet should be familiar to the crew as it is similar to the hole 'n hose model the station has employed since 2000, but it is designed to allow for more privacy. As water is notably scarce in orbit, the ability to generate an onboard source of it is very important. The US-made filtration system separates water molecules from waste by not letting anything larger than tiny water molecules through.

The fancy new space toilet comes as part of a $46 million upgrade package purchased by NASA. So far, the single toilet on the Russian half of the station is responsible for the crew of three. As the crew size will double to six in 2009, NASA no doubt saw the need for a additional toilet. Six people, one bathroom? Think the Brady Bunch, but in space. If Marcia takes too long dolling it up for the cosmonauts, Jan doesn't bang on the door and yell. She jettisons her.
