New Products: April 2017 Aerospace & Defense Techonology

Rate Indicator/TotalizerThe Hoffer (Elizabeth City, NC) HIT-4U Rate Indicator/Totalizer is being offered with additional options providing the user with enhanced functionality and flexibility in a compact enclosure. The choice of a NEMA 4X enclosure joins the explosion-proof enclosure options and is now available flow meter mounted or remote mounted on a 2" or smaller pipe. The NEMA 4X enclosure offers options for local Modbus access ports via USB port or hardwired access through strain relief for data log retrieval and configuration of the unit.Additional user friendly features of the unit include 12-point linearization, dual set point alarm output configurable for rate or total and a wide range of engineering unit display icons. The HIT-4U is offered in battery or loop-power with a lithium battery backup to ensure continuous, reliable performance.

Morphing Wings Make Jets More Efficient

University of Michigan engineers have developed improved wing designs capable of burning less fuel, as well as tools that help the aerospace industry build more efficient aircraft. In areas where new technologies are being applied – such as for wings made of composite materials or wings that morph during flight – improved design tools can provide insights when intuitive understanding is lacking.

NASA Tests Engines That Reduce Drag and Fuel Burn

Boundary Layer Ingestion (BLI) is a promising idea NASA researchers are studying to reduce fuel burn in jet engines, thus reducing emissions and the cost of operating the aircraft. Thrust makes an airplane go forward, while drag tries to slow it down. Lift offsets the weight to keep an airplane in the sky. BLI deals specifically with the drag part of the equation by trying to reduce the total drag an airplane experiences in the sky.

NASA Test Flights Will Study Improved Efficiency of Supersonic Aircraft

NASA is set to begin a series of supersonic flights that will examine efforts to improve the efficiency of future supersonic aircraft. Future supersonic aircraft seeking to achieve a low boom will rely on a swept wing design in order to fly at supersonic speeds without producing a loud sonic boom. The swept wing design generally produces airflow disturbances that run along the span of the wing, resulting in turbulent flow, increased drag, and ultimately, higher fuel consumption.

Language Learning Robot Could Advance Autonomous Vehicles

A Purdue University researcher and his team are developing technology to give robots the ability to learn language. A team led by Jeffrey Mark Siskind, associate professor in Purdue’s School of Electrical and Computer Engineering, has developed three algorithms that allow a wheeled robot to learn the meanings of words from example sentences that describe example paths taken by the robot, to use the words to generate a sentence to describe a path of movement, and to comprehend the sentence in order to produce a new path of movement.
