General Atomics Aeronautical Systems, Inc. (GA-ASI) is using an integrated fuel tank structure to maximize fuel offload for the proposed MQ-25 unmanned aerial refueling aircraft for the U.S. Navy. GA-ASI applied its knowledge of advanced composite aircraft structures to develop integrated fuel tanks in a large-scale wing box test article and a full-scale wing skin pre-production validation article.

Space Debris Orbit and Attitude Prediction for Enhanced and Efficient Space Situational Awareness

This research deals with the problem of modelling the orbit and attitude motion of uncontrolled manmade objects in orbit about the Earth, which tumble due to the natural influences of the near-Earth space environment. A mathematical, physics-based and computational approach is taken to model the forces and torques that drive the orbit and attitude evolution of such objects. The main influence modelled is solar radiation pressure (SRP), which is the interaction of solar electromagnetic radiation with the surface of an object, leading to both forces and torques that influence the orbital and attitude motion. Other influences, such as the gravitational field of the Earth, are also modelled.

Enhanced SATCOMs for Unmanned Aerial Systems

Satellites launched with the purpose of relaying communications have been enabling around-the-globe transmissions of information for half a century. And in this current era of hybrid warfare, that means this decades-old hardware needs to be able to manage the command and control of unmanned aircraft.

New Products: September 2018 Aerospace & Defense Technology

Pin Fin Heat Sinks

Advanced Thermal Solutions, Inc. (ATS) (Norwood, MA) has a family of Pin Fin heat sinks designed as cost-effective solutions for systems with adequate airflow. The high aspect ratio design enables ATS Pin Fin heat sinks to provide low thermal resistance from base to fins in systems where the airflow measures 200-plus LFM (linear feet per minute). The cross-cut design also allows the Pin Fin heat sinks to be effective in systems where airflow is ambiguous.

Communicating from Space: The Front End of Multiscale Modeling

As satellites and astronauts travel further out in space, the more communication challenges they face. NASA launched the InSight Mission on May 5, 2018 from Vandenberg Air Force Base, California. InSight was designed to collect data on Mars quakes and the processes that shaped the rocky planet to help us better understand how it formed. Getting the information back to the scientists here on Earth required a variety of antennas on the spacecraft.

Designing a High-Speed Decoy Unmanned Aerial Vehicle (UAV)

Drone aircraft and their uses have been evolving quickly, supported by a great deal of ongoing research. One area of increasing interest is the decoy drone, designed to mimic the radar and heat signature of an actual aircraft. These drones are intended to confuse or mislead anti-aircraft defense systems. If operating as designed, one or more drones are launched from an actual aircraft as it enters airspace monitored by anti-aircraft systems. The system picks up the signature of the drones and attacks them while the actual aircraft can be hidden with the swarm of drones.

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].

Aircraft Scheduling Models Ease Traveler Frustration

Flight schedules that allow for a little carefully designed wiggle room could prevent the frustration of cascading airport delays and cancellations. By focusing on the early phases of flight schedule planning and delays at various scales, researchers have developed models to help create schedules that are less susceptible to delays and easier to fix once disrupted.

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.
