X-51A WaveRider hypersonic mission doomed by bum missile fin

DNP X51A Waverider hypersonic test fails with snapped fin before scramjet deployed

The latest attempt to go past Mach 5 with the X51A has finished badly again, as a broken fin caused the missile to lose control before its air-breathing "scramjet'" motor could even kick in. It happened just after the booster rocket phase, which accelerates the craft to at least Mach 4, a high enough velocity for the hypersonic scramjet to work. The craft ended up in the Pacific shortly afterwards instead, and this latest affair may end up dunking the entire $300 million program. The Air Force initiative is already short on funding, and the previous two tries were equally dismal failures -- meaning a fourth missile, already built, may end up a museum piece.

NASA’s X-48C hybrid wing-body plane completes first test flight

NASA's X48C hybrid wingbody plane completes first test flight

After planting a rover firmly on Mars' surface and testing a new methane-fueled lander, NASA has squeezed in the first test flight of its X-48C hybrid wing-body aircraft. Thanks to its design, which combines those of flying-wing and conventional planes, the X-48 could offer 20 to 30 percent more fuel-efficiency, greater fuel capacity and a quieter ride in its final form than traditional craft. The finished model has a projected range of 11,000 nautical miles and a 240-foot wingspan. As an 8.5 percent scale of the full-sized airplane, the remotely piloted prototype weighs in at 500 pounds with a 20-foot wingspan. During the test, it successfully took to the skies for nine minutes and peaked at an altitude of 5,500 feet -- though it's capable of soaring for 35 minutes and climbing nearly twice as high. Another version of the craft (likely with a human behind the flight stick) is estimated to be at least four years down the road, and the final model isn't expected to arrive for another decade.

Lockheed Martin F-35 Lightning II stealth fighter cockpit demonstrator hands-on (video)

Lockheed Martin F35 Lightning II stealth fighter cockpit demonstrator handson video

We spend hundreds of hours on board a variety of airplanes each year, most often en-route to a trade show or product launch event, but occasionally we have a rare opportunity to hop on board military aircraft, to test out unrelated products, or, even more unusually, to take a seat behind the yoke. Sadly that's not what we're doing today -- well, not exactly. We are taking a closer look at the F-35 fighter jet at Lockheed Martin's Fighter Demonstration Center just outside our nation's capital, but, being in the middle of a corporate complex, there's no actual Lightning II on hand. We were able to take a simulated ride, however -- this isn't your ordinary 4D sickness-inducing amusement park thrill. The F-35 is by far the most advanced Lockheed jet to date, with updated radar, all-internal weapons, improved tracking systems, 360-degree infrared coverage with a visor readout, and a full-stealth design, not to mention the incredibly capable glass cockpit powered by more than 9.3 million lines of software code, and an overall smoother experience for pilots that could end up spending shifts of 12 hours or longer in flight.

The F-35 has already seen plenty of field time in the US, with more than 500 flights already in 2012, and it's set to make its way to the UK armed forces next week and the Netherlands later this year, but while the aircraft is quite familiar to the pilots tasked with flying it, the public hasn't had an opportunity to experience Lockheed's latest airborne warrior. We flew a simulated mission within a grounded duplicate of the flyable F-35 cockpit, and the capabilities and improvements are quite clear -- you definitely don't want to encounter an F-35 from a previous-generation aircraft. The dual 8 x 10-inch touch-enabled displays combine to give you 8 x 20 inches of real estate, with dedicated modules for the weapons systems, targeting, and navigation easily accessible -- you can also move them to different panels depending on your current objective. A pair of joysticks at the left and right side provide direct access, letting you move a cursor to track enemy crafts or ground-based targets as well, and a very slick heads-up-display mounted in the helmet provides infrared mapping and instrument readouts. Overall, it seems to be an incredibly powerful system. Unfortunately, the mock-up on display here isn't accessible to the public, but you can join us for a behind-the-scenes look just after the break.

X-37B finally touches down, completing its not-so-secret classified mission (video)

X-37B finally touches down, completing its not-so-secret classified mission (video)

After more than a year of circling the globe, the US Air Force's X-37B has finally touched down at Vandenberg Air Force Base in California. The unmanned, reusable space plane spent 469 days in orbit, performing a number of experiments (many of which are classified) before finally ending its lengthy run Saturday. What exactly the military has learned from the extended orbital excursion is unclear, but, like the Mars rovers before it, the X-37B turned out to be far more robust than many had anticipated. Its mission was originally intended to last just nine months, but its operators managed to milk about six more months out of the craft. While we wait to find out what the next step is, enjoy the video of it landing after the break.

Batman Grappling Hook Gun Created at BYU

Of all the gadgets and gizmos that Batman uses to fight crime, one of the ones I always thought was most interesting was his grappling hook gun that he can fire up onto ledges or the top of buildings to climb. If you’ve ever wanted to have that sort of grappling hook gun, some student engineers at BYU have created one that actually works. The students dreamed it up based on what Batman uses.

grappling gun byu

The students created their grappling hook gun for an Air Force competition. The device the team created uses a launcher to shoot a grappling hook as far as 90 feet in the air. Once deployed, the system uses pulleys, and other tech to automatically pull the user up the building or other surface with little effort.

The contest the team will be participating in gives them 20 minutes to demonstrate the tool and then train military representatives on its use. The goal of the competition is to get three people up a 90-foot vertical incline while carrying 300 pounds of gear each. The device designed by the BYU students is able to climb 30 feet per minute. Check out the video above to see the system in action.
