Insect-Inspired Micro-Drone

A flying robot, developed by TU Delft researchers, is an autonomous, free-flying and agile flapping-wing micro-drone. Inspired by fruit flies, the robot’s control mechanisms have proved to be highly effective, allowing it not only to hover on the spot and fly in any direction, but also be very agile. The robot has a top speed of 25 km/h, can perform aggressive maneuvers, and provides 5 minutes of hovering flight or more than a 1-km flight range on a fully charged battery.

Wing Anti-Frosting Fights Ice with Ice

A passive anti-frosting surface was developed that keeps surfaces 90 percent dry and frost-free indefinitely – all without any chemicals or energy inputs. The anti-frosting surface was tested on untreated aluminum by patterning ice stripes onto a microscopic array of elevated grooves. The microscopic grooves act as sacrificial areas, where stripes of intentional ice form and create low pressure zones.

New Products: October 2018 Aerospace & Defense Technology

Microstepping Motor Driver

US Digital (Vancouver, WA) announced the release of the MD3 Programmable Microstepping Motor Driver, capable of driving motors from NEMA size 14 to 42. The MD3 accepts 9-50 VDC power inputs and is rated for currents up to 7A continuous duty. In addition to digital input controls, the MD3 can be configured and controlled using the open MODBUS RTU protocol over a RS485 bus. A GUI application is supplied that allows many settings to be changed including the number of microsteps per full step, acceleration/deceleration rates, speed and current cutback. The design supports multiple MD3 units on the same RS485 bus and allows for programmable motion profiles. In addition, the MD3 has a brushed DC motor speed control mode.

Using Electromagnetic Brakes to Keep Thrust Reversers IN PLACE

Applying reverse thrust redirecting engine power to oppose the direction of travel is a standard technique for decelerating aircraft after touchdown. The approach saves wear on the brakes of the landing gear wheels and reduces stopping distance. Although accidental deployment of the thrust reverser cowl could and did happen, it was assumed for decades that this would only present a hazard in the moments around takeoff and landing. With changes to engine design and aircraft aerodynamics, this assumption no longer held, as demonstrated by the catastrophic loss of Lauda Air Flight 004.

Digital Transformation for a CONNECTED ENTERPRISE

Manufacturers around the world are grappling with the challenge of continuous innovation in the face of increasing complexity. In aerospace and defense (A&D), complexity is nothing new, but digital transformation to become a more connected enterprise that allows programs to run independently while achieving enterprise-wide processes remains an elusive goal. Today, organizations around the world are rethinking their strategies and turning to more open and agile approaches to create a connected enterprise that can enable faster innovation.

Thermostatic Solutions for Temperature Control Applications

The wax-filled thermostatic element was invented in 1936 by Sergius Vernet (1899-1968). Its principal application was in automotive thermostats used in the engine cooling system. Wax thermostatic elements transform heat energy into mechanical energy using the thermal expansion of waxes when they melt. In addition to engine cooling systems, this wax motor principle also finds applications in heating system thermostatic radiator valves, plumbing, industrial, and agriculture. Today this technology is widely used across a broad spectrum of industries including aerospace & defense, most often for temperature control of various fluid systems.

Bringing RF into the Embedded World: It's Time

Embedded systems have been almost entirely digital throughout their long history, while RF and microwave technologies were separate subsystems with no effective interface between the two. For many reasons, this “RF/digital divide” should finally be connected.
