The UK launches a 3D printed airplane drone

10:01 am

A University of Southampton team, under a project for the Royal Navy of the United Kingdom, have built and launched an entirely 3D printed unmanned air vehicle (UAV) from a navy ship.

Produced under the institution’s Project Triangle, the Southampton University Laser Sintered Aircraft (SULSA) UAV was launched via catapult from the patrol vessel HMS Mersey, and flew over the Wyke Regis training facility near Weymouth in the south of the country to land on Chesil beach. The 5min sortie covered a range of some 500m, with the UAV carrying a small video payload to record the mission so that operators could monitor it during the flight.

SULSA measures 150cm (59in) and weighs 3kg (6.6lb), and is made via 3D printing using laser sintered nylon. The university claims that SULSA is the world’s first UAV made entirely via the technique. It consists of four separately manufactured main parts that are assembled without the need for any additional tools.

The specific achievement here is interesting, but its significance in illustrating the growing use of unmanned drones and 3D printing is more important. Very soon, a large percentage of everything we own will be built with 3D printing technology, lowering the cost while making construction easier. As for drones, they carry both positive and negative possibilities.

Two Eagles manned balloon breaks record

4:09 pm

The privately funded Two Eagles manned balloon has set a new endurance record as it drifts parallel to the west coast.

The team is making good progress in its flight parallel to the west coast of the United States and is now approximately 400 miles west of the Mexican border. It is still expected the landing will occur tomorrow (Saturday) morning on the Baja peninsula in Mexico. Pilots Leonid Tiukhtyaev (two-kh-TIE-yev) and Troy Bradley and the Mission Control team will be very busy during the final hours of the flight using winds at different altitudes to steer the balloon to a safe landing in Baja.

FAA moves to regulate and thus destroy drone use

1:47 am

We’re here to help you: The FAA is considering a new rule to require a pilot’s license in order to operate a private drone, even drones more akin to model airplanes.

The proposed rules would require that a drone owner would have to get certified as a pilot, “certification that can cost $10,000 and demand many hours flying aircraft that control nothing like a little drone.”

“Knowing the proper flap setting on a short runway approach for a Cessna 172 doesn’t do any good for a DJI Phantom [an inexpensive and popular commercial drone],” said Matt Waite, a University of Nebraska professor and founder of the Drone Journalism Lab. “A lot of people out there already running businesses in conflict with FAA policy, who don’t have pilot licenses, are probably looking at this like, ‘You’ve got to be kidding me.'”

Gee, here we have a new industry that is growing and prosperous, with many people coming up with creative ideas for using drones that none of its inventors ever dreamed of, and the government wants to step in and control it, regulating it to a point where it can’t even exist legally. Isn’t that nice of them?

The 707 turns 60

12:11 am

The sixtieth anniversary of Boeing’s 707 passenger jet and how it changed aviation history.

The pictures are cool, but read it for the history. Sixty years ago the ability of ordinary citizens to span the globe quickly and easily suddenly became possible, and that ability has changed the world.

The solar-powered experimental airplane Solar Impulse 2 made its maiden flight on Monday.

10:08 am

The solar-powered experimental airplane Solar Impulse 2 made its maiden flight on Monday.

The solar-powered aircraft took off at 5:36 AM CET, when the weather around the aerodrome was at its calmest, with pilot Markus Scherdel at the controls. The aircraft flew for two hours and 17 minutes, reaching an altitude of 1,670 m (5,500 ft) and a ground speed of 55.6 km/h (30 kt). According to Solar Impulse, the in-flight data indicates that the aircraft slated to make the first all-solar global circumnavigation flight performed to expectations.

The goal is to use this plane to fly around the world in 2015. Videos of the take off and landing below the fold. The plane gets off the ground very quickly, does not move very fast, and is balanced precariously on a single set of wheels in the center. If you look closely before takeoff, there are two guys literally holding the wings up at each end to balance it. They have to run with the plane for the first few seconds until it gets enough lift to balance on its own. The landing video shows both bicyclists and men racing to meet up with the wings to hold them up once the plane stops.

To save fuel United Airlines is adding additional winglets to the wingtips of their airplanes.

2:18 pm

To save fuel United Airlines is adding additional winglets to the wingtips of their airplanes.

The radical re-sculpting of traditional winglets adds a new tip below the upturned one that sharply curve backwards like a scimitar. That further reduces wingtip vortices that drag on the wingtips. Each traditional pair of winglets on the 737 cuts fuel consumption by 3.5% to 4% on flights of more than 1,000 nautical miles. The split scimitar upgrade—which costs $545,000, before discounts–will reduce fuel burn by up to 2% more, says United, which hopes to save up to $60 million a year because of the devices, once its fleet is outfitted.

Very smart. Expect to see these winglets appear on all commercial jets in short order.

The FAA has lifted its ban on the use of cell phones during take-off and landings in airplanes.

1:01 pm

The FAA has lifted its ban on the use of cell phones during take-off and landings in airplanes.

The ban on mobile devices has been in effect since the early 1990s, when cellphones began to crop up, and the FAA and airlines summarily freaked the hell out for no good reason. Despite no direct evidence that the use of mobile phones or other electronic devices would interfere with the plane’s systems, the ban continued — even after the FAA hired an outside safety agency to find if anything could go wrong. They didn’t. But the FAA and airlines decided to continue the policy. Until today.

The requirement to stow laptops during takeoffs and landings remains, however, as the FAA fears these larger objects could too easily become dangerous projectiles should something go wrong.

Engineers in the Czech Republic have built a bicycle that can fly.

11:17 am

Engineers in the Czech Republic have built a bicycle that can fly.

The demonstration does beg the question “Why a bike?”. Once those big, knobby tires are lifted off the ground, aren’t they rendered more or less moot? According to the project website, the central concept was to create a flying vehicle that could easily be ridden to a more suitable takeoff site and then be capable of a 3 – 5 minute flight. In order to offset the extra weight added by all the rotors, they could be used to help propel the bike along the ground, besides allowing it to fly.

Solar Impulse has completed the second leg of its journey to fly across the United States powered only by the sun.

10:50 am

Solar Impulse has completed the second leg of its journey to fly across the United States powered only by the sun.

The Solar Impulse has broken its own record for the longest distance flight of a solar-powered aircraft following the second leg of its journey across the USA. Solar Impulse touched down in Texas at 1:08 a.m. local time after a flight of 18 hours 21 minutes having covered at least 868 miles (1,397 km). Two different distances have been reported for the flight. The Solar Impulse website says the flight “amounted” to 868 miles (1,397 km). However, according to a Phys.org report, Solar Impulse covered a distance of 1,541 km (which it rounds to 950 miles, though this is not the precise conversion).

It is thought the two distances exist because the plane actually lost ground during part of its flight due to headwinds.

A solar-powered airplane landed safely in Phoenix today on its first leg of an attempt to fly across the United States.

A solar-powered airplane landed safely in Phoenix today on its first leg of an attempt to fly across the United States.

I totally support this effort to develop new technology, but must note that the capabilities of this solar-powered plane, as described in this article, are woefully limited. Nonetheless, I can see many applications where these liabilities will not be an issue, so all power to them. I hope they succeed.
