Let the Good Times Continue to Roll

It is hard to imagine just how radical the change in fortunes for the world’s major commercial aerospace manufacturers has been in the last few years. Just ten years ago the smart money in aerospace pointed to the defense sector as the best source of future profitability. But just as this was reaching a peak, the full impact of a near meltdown in global financial markets brought home to Western governments that defense budgets couldn’t just keep on expanding and a new era of military program cuts began.

Big Data, Aircraft, and a Better Future

The hype phrase today is “Big Data.” It is a phrase Mark Bünger, Research Director for Lux Research, believes can have a number of definitions depending on who is doing the defining. Bünger was the lead analyst on a report that Lux published in April 2015 that surveyed both the technology as it is today and how various industries are adapting to the opportunities—and perils—in trying to exploit it.

Unmanned Ground Vehicle Communications Relays

The need for a high-bandwidth communication link to carry multiple video channels from a mobile robot (unmanned ground vehicle, or UGV) back to a control station requires using high-frequency RF communication links. These links are mostly line-of-sight, often limiting the flexibility of the robot’s movement. The Autonomous Mobile Communication Relays project demonstrated the capability of autonomous slave robots to provide communication-relaying capability for a lead robot exploring an unknown environment.

System Generates and Simulates Skin-Echo Pulses for Radar Testing

One of the methods for radar testing is the simulation of an environment where there are dynamic or static objects that are scanned by the radar under test. In particular, simulation implemented by MPG Instruments (Rome, Italy) generates skin-echo pulses coming from radar that transmits a defined pattern stream. The system simulates an object in the scanning area of the radar and is hit by a pulse pattern stream. The X-band radar must be tested at a frequency from 7 GHz to 12.5 GHz, and K-band between 12 GHz and 40 GHz.

High-Strength Aluminum Powder Developed for Additive Manufacturing in Aerospace, Automotive

Metal laser melting has made a successful leap from rapid prototyping to an approved manufacturing technology, and the method is increasingly becoming an option for companies in high-tech industries, according to Toolcraft. And now the German manufacturer has teamed with Airbus APWorks to offer another option for additive manufacturing—the Airbus subsidiary’s Scalmalloy high-performance aluminum powder.

Propulsion Performance Model for Efficient Supersonic Aircraft

For the design process of the class of aircraft known as an efficient supersonic air vehicle (ESAV), particular attention must be paid to the propulsion system design as a whole including installation effects integrated into a vehicle performance model. The propulsion system assumed for an ESAV considered in a recent study done by Optimal Flight Sciences LLC and the Air Force Research Laboratory was a three-stream variable cycle engine (VCE).
