FAA issues study on drone/human collision hazards

What could happen if a drone hit a person on the ground? What’s the risk of serious injury? Can those risks be reduced? Although the Federal Aviation Administration (FAA) can’t yet definitively answer those questions, studies by a consortium of leading universities have begun to better understand the risks associated with flying small unmanned aircraft (drones) over people and things on the ground.

Engineers investigate simple, no-bake recipe to make bricks from Martian soil
Explorers planning to settle on Mars might be able to turn the planet’s red soil into bricks without needing to use an oven or additional ingredients. Instead, they would just need to apply pressure to compact the soil -- the equivalent of a blow from a hammer.

Wings:
Sikorsky/Boeing future vertical lift rotorcraft

The Sikorsky/Boeing Future Vertical Lift concept is a scalable design based on proven X2 Technology, which aims to double the speed of current military helicopters. Designed for long-range, high-speed, superior hover performance and unmatched maneuverability, the Future Vertical Lift program will shape the U.S. military’s helicopter fleet of the future, initially by replacing the Blackhawk and Apache helicopters. The design with working prototypes focuses on vibration reduction, weight reduction, and blade technology; features fly-by-wire technology; and even incorporates elements of the Joint Strike Fighter jet airplane. The RAIDER light tactical prototype helicopter is capable of carrying six troops and external weapons at 276 mph. The DEFIANT Joint Multi-Role Technology Demonstrator helicopter will prove the scalability of the X2 design to a 30,000-lb. class weight.

Space: 3 years after disaster, Virgin Galactic tests new spaceship feather system
Almost three years after the in-flight breakup of SpaceShipTwo VSS Enterprise on Oct. 31, 2014, Virgin Galactic has completed a successful first test for feather flight for its VSS Unity spaceship. Untimely unlocking of the feather system, which was designed to pivot the tailboom structures upward to slow the vehicle during reentry into the Earth's atmosphere, was blamed for the incident in 2014 that killed one of two pilots. A new "control inhibit" feature should prevent that from happening again. The latest test flight was the fourth glide flight (and eighth flight overall) of VSS Unity. In Virgin Galactic's concept, a passenger-carrying suborbital SpaceShipTwo vehicle is carried by a mother ship, the WhiteKnightTwo dual-fuselage jet aircraft, up to an altitude of around 50,000 ft for air launch, where it reaches supersonic speed within 8 sec powered by a hybrid rocket motor. It cruises into the lower thermosphere almost 70 miles up before performing reentry and then landing back on Earth.

Light pipes used in jetpack controls
Here's a neat application for you: LPC rigid light pipes from VCC were used in an advanced jetpack pilot warning display. Light pipes (light guides) transmit light from an LED mounted on a PCB board to the user interface to communicate vital information. The light pipes offer design flexibility, easy installation, and multiple LED packaging options. The LPC rigid light pipe was selected due to its rugged material, easy assembly, superb daylight visibility, and wide 160-deg viewing angle.

Image - New adhesive for optoelectronic applications
New adhesive for optoelectronic applications
DELO has introduced a new adhesive for optoelectronic applications (components that convert electrical energy into light and vice versa). DELO DUALBOND OB786 is ideal for fixing components within seconds, while ensuring precision and high strength. This milky epoxy resin with medium viscosity ensures good adhesion to common substrates like aluminum, FR4, PPS, and LCP. This product cures under UV light but can be set in a convection oven for areas where light doesn't reach. Great for LED lens bonding, wafer-level/micro-optics, mini cameras, and more.

Training for NASA-proven composites design software
As the use of composite materials grows in aerospace, automotive, transportation, wind, shipbuilding, and other industries, so must the skills of the designers and engineers charged with producing digital models that are lighter and stronger -- and manufacturable. HyperSizer software, the first ever to be commercialized out of NASA in 1995, is the focus of a five-day training course being offered June 12-16 in a dedicated facility near Collier Research’s Newport News, VA, headquarters. The course is suitable for both novice and experienced HyperSizer users. By the end of the week, attendees will be able to use both Pro and Express versions of HyperSizer and perform use cases for analysis and design optimization.

Scientists identify chemical causes of lithium-ion battery 'capacity fade'
When a battery enters "old age," scientists refer to its diminished performance as "capacity fade," in which the amount of charge a battery can supply decreases with repeated use. Capacity fade is the reason why a cell phone battery that used to last a whole day will, after a couple of years, last perhaps only a few hours. But what if scientists could reduce this capacity fade, allowing batteries to age more gracefully?

Great Concepts: Next-gen expanding-wheelbase skid steer
It's all about leverage! A company called Extend Manufacturing has created an ingenious proof-of-principle expanding-wheelbase skid steer machine called the Pro-Handler that solves many of the problems faced when using these types of loaders/fork lifts, including handling heavier loads and not tipping over. The reach on the prototype has also been lengthened with an extendable boom, so there are pluses all around for this concept's design. The extensions are done hydraulically with four extra cylinders and telescoping tubes with frictionless pads. Check out all the details on Extend Manufacturing's Fundable page, and watch the video to see it to believe it.

Air knives for cooling, drying, and blow-off
Air Knives from Vortec amplify ordinary compressed air 25 times over its input into a uniform, high-velocity laminar air sheet ideal for blow-off of water and debris, static neutralizing, and some high-speed drying or cooling applications. With no moving parts and no power source, these air knives are inherently safe. Available in 3-, 6-, 9-, 12-, 18-, and 24-in. lengths, these proven designs produce increased thrust and velocity, reduced noise, instant on/off, and excellent uniformity. A single, 1/4-in. NPT compressed air inlet will feed up to a 12-in. air knife.
