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.

Maintaining Enterprise Resiliency Via Kaleidoscopic Adaption and Transformation of Software Services (MEERKATS)

This research investigates a new vision for increasing the resilience of computing clouds by elevating continuous change, evolution, and misinformation as first-rate design principles of the cloud's infrastructure. The work is motivated by the fact that today's clouds are very static, uniform, and predictable, allowing attackers who identify a vulnerability in one of the services or infrastructure components to spread their effect to other, mission-critical services. The goal is to integrate into clouds a new level of unpredictability for both their services and data so as to both impede an adversary's ability to achieve an initial system compromise and, if a compromise occurs, to detect, disrupt, and/or otherwise impede their ability to exploit this success.

Burner Rig Testing of A500® C/SiC

There is growing interest in developing, testing, and deploying ceramic-matrix composites (CMCs) into commercial and military aerospace gas turbine engines due to their durability under extreme conditions and weight-savings potential. For military applications, the focus is on the afterburning section of the turbine engine, including the flameholder, augmentor liner, and both the convergent and divergent segments of the exhaust nozzle. These are demanding applications because of the high temperatures and rapid thermal cycles.

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.

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.
