Russia looks to develop advanced rotary-wing UAV test bed

Russia’s advanced research projects agency is launching a programme for the development of a rotary-winged unmanned air vehicle testbed, which will be used by government agencies to assess advanced robotic technologies for the military.

An announcement from the agency issued on 14 April says it is looking for parties to create a “flying laboratory” UAV, which will explore what it describes as “complex, multidiscipline” technologies necessary to advance autonomous flight.

“Testing using the flying laboratory, looking [at] orientation and vision systems [and] automatic piloting and group interaction algorithms, is an important area of work for the creation of advanced scientific and technological potential in the field of robotic airborne devices," Vitaly Davydov, deputy general director and chairman of the agency’s scientific and technical council, says.

The agency is collaborating with the Russian department of scientific research and technological support of advanced technologies – plus the Russian defence ministry – on the project.

“During the upcoming competition, we plan to identify that developers can solve these scientific and technical problems with high quality and within a reasonable time,” Davydov adds.

A workshop was held in March which assessed examples of currently available autonomous UAVs, plus the challenges and technical requirements needed for their advancement.

It saw 50 Russian companies gather to explore the technology, and concluded creating highly-manoeuvrable, multirotor UAVs with a maximum take-off weight of 5kg (11lb), and up to 0.5m in length, is a “difficult task”.

“There are a number of problems: from the choice of the aerodynamic circuit, power supply capable of a flying time of at least 60min, and ending with an integrated vision system, including elements of artificial intelligence,” the agency says.

The agency was established in 2012, and is Russia's answer to the US Defense Advanced Research Projects Agency, that looks to develop future military technologies.

The World’s Hugest Jet Engine Is Wider Than a 737’s Fuselage


GE Aviation spent $10 million preparing its Peebles Test Operation in Ohio for the GE9X. Improvements include the largest “bellmouth inlet duct”—the white funnel attached to the front of the engine during testing.GE AVIATION

GE designed the behemoth specifically for the Boeing777X widebody airliner expected to take flight in 2020. The engine uses 3-D printed components, composite materials, and redesigned fan blades and air routing to deliver a staggering 10 percent increase in fuel efficiency without sacrificing power or reliability. That’s a Herculean feat in a field where engineers would step over their own mothers for a one percent bump.
Bigger is better here mostly for the sake of efficiency and noise. A larger fan draws more air with less energy, as long as you’re mindful of the aerodynamics and keep weight to a minimum. Larger fans make for quieter engines, too, because they distribute airflow over a greater area. GE wants to send as much air as possible around the engine’s core rather than through it. Engineers call that bypass flow. Bigger fans make it possible. The GE9X boasts a bypass ratio of 10:1, compared to the old engine’s 7.5:1.
(This also explains why fighter jets are so loud: They’re basically engine cores with wings, and their engines use small bypass ratios so they fit within smaller airframes. This also is good for power but terrible for fuel efficiency.)
GE engineers designed carbon fiber blades to minimize weight, and some aerodynamic tweaks to increase their ability to withstand high-speed airwaves during flight. “We modeled huge blades to pull massive amounts of air into the engine while operating at low noise levels,” says project leader Chuck Jackson.1 “Traditional titanium blades at this size would have added too much weight.”

Solar Impulse 2 lands in desert after soaring in Silicon Valley
Aircraft is attempting the first around-the-world solar trek. It's stopping in US destinations, including Silicon Valley, Phoenix and New York.


The goal of the Solar Impulse 2, which doesn't use fuel or release polluting emissions, is to prove the benefits of solar technology and help wean the world off its reliance of fossil fuels. The pilots are on a quest to complete the first around-the-world trip in a solar plane. The 5,500-pound plane, which travels about 47 miles per hour, is powered by 17,248 solar cells built on the wings. They convert sunlight into electricity to power the four electric engines and propellers.

The previous two posts are not explicitly defence technologies, but they could have potential defence applications. The focus is not innovative technology that can have impact in the defence field.

A solar powered aircraft can be, for example, a potential loitering munition.
