The Bus Too Tough to Die

The venerable MIL-STD-1553B bus has survived remarkably well even as other more advanced solutions gained wide acceptance in the last few years. However, the fact remains that its maximum data rate of 1 Mb/s is orders of magnitude too slow for today’s data-intensive systems, so logic dictates that it will soon fade away. That may be a logical assumption, but it’s likely to prove wrong, for several reasons.

Using Thermoplastics in Aerospace Applications

In August 2017, Qantas Airlines laid down the challenge to both Boeing and Airbus to offer an aircraft that can cross one of aviation's “last frontiers.” That “last frontier” was an aircraft capable of flying an economical passenger load non-stop for over 20 hours. This would allow Qantas to offer direct service from Sydney to London or New York. Weight reduction through the use of thermoplastics and other technologies would be the key to any chance of success in this endeavor.

New Products: August 2018 Aerospace & Defense Technology

Barometric Pressure Sensor

Bosch Sensortec (Reutlingen, Germany) has introduced a new high performance barometric pressure MEMS sensor, the BMP388. The BMP388 delivers outstanding altitude stabilization in drones, where accurate measurement of barometric pressure provides the essential altitude data for improving flight stability and landing accuracy. The new barometric pressure sensor is part of Bosch Sensortec's comprehensive sensor solution for drones, which includes the BMI088 Inertial Measurement Unit (IMU) for accurate steering and the BMM150 geomagnetic sensor for the provision of heading data.

Using Turbine Flow Meters for Aerospace Test and Measurement Applications

Turbine flow meters have long been a preferred technology for obtaining precise measurements of fluid flow in the aerospace industry. In addition to their high accuracy, they are recognized for exceptional turndown, repeatability and speed of response.

In-Flight Real-Time Avionics Adaptation

Avionics is a very restricting domain for obvious safety reasons. Along with miniaturization comes the idea of integration. More functionality on one spot requires a good management of privacy and congestion on shared platforms. This is why determinism is one of the keywords of avionics works. This led to protocols like ARINC653[1] assuring that multitask embedded programs respect a predictable policy applied by the operating system (OS). Another key protocol is ARINC664, which guarantees that multiple communicating systems efficiently share the network. These two protocols are pillars of the Integrated Modular Architecture (IMA) concept[2].

AgilePod Flies on U.S. Air Force MQ-9 Reaper

In March 2018, the Air Force Life Cycle Management Center’s Sensors Program Office, working jointly with the AFLCMC Medium Altitude Unmanned Aerial Systems Program Office, sponsored three demonstration flights of an MQ-9 Reaper with AgilePod. The flights were a first for AgilePod on an Air Force major weapon system, and were the result of collaboration between AFLCMC and the Air Force Research Lab.

“These flights mark the culmination of more than two years of cutting-edge technology development led by our colleagues within the Air Force Research Laboratory’s Materials and Manufacturing Directorate ManTech team, and Sensors Directorate Blue Guardian team,” said Lt. Col. Elwood Waddell, the advanced technologies branch chief within the Sensors Program Office.”

Non-Contact Method Measures Aircraft Internal Stresses

Scientists have developed a non-contact method of internal voltage control in polymer composites, making it possible to assess the degree of internal damage during the operation of aircraft parts. The method uses amorphous soft magnetic circuits to assess the stress state in composite materials. Wires are laid between the carbon fiber layers, forming a stress-sensitive grid.

Meeting Environmental Objectives and Regulations

Gone are the days when the impact of products on the environment or human health were optional business concerns. Regulatory constraints on materials and chemicals are increasing, and many companies struggle to respond – and to do so quickly and efficiently. Restrictions on hexavalent chrome are one well-known example. Another is REACH – the European Union regulation concerning the Registration, Evaluation, Authorisation & restriction of Chemicals – which applies to products that are either manufactured in, or imported into, the EU. Companies are under obligations to report the use of restricted substances, and to limit or avoid their use.
