University Opens New Ballistics and Impact Dynamics Lab

Wichita State University’s National Institute for Aviation Research recently opened a new ballistics and impact dynamics research lab in the former Britt Brown Arena at the Kansas Coliseum. The new ballistics lab, part of NIAR’s environmental Test Labs, uses a custom built ballistic firing device to propel 22-50 caliber rounds into components inside a concrete containment building. The test is designed to simulate the impact of a structural failure on the aircraft.

Cable Installation Simulator

A cable installation simulator from W. L. Gore & Associates aids in evaluating the stress of installation on microwave airframe assemblies, thereby minimizing the risk of cable assembly damage or failure during installation. By comparing signal integrity before and after installation, Gore can engineer assemblies that withstand airframe installation as well as the demands of the aircraft’s flight envelope. Use of the installation simulator gives aircraft manufacturers and installers evidence that their assemblies will provide the same level of electrical performance after installation as when they are new.

Reaching the Benchmark in Secure Unmanned Vehicle Software

Security concerns currently dominate software thinking wherever sensitive or safety-critical information is potentially accessible. Embedded software is no exception. Security researcher Barnaby Jack demonstrated this in 2011 when he used a modified antenna and software to wirelessly attack and take control of Medtronic’s implantable insulin pumps. He demonstrated how such a pump could be commanded to release a fatal dose of insulin. Obviously, that vulnerability puts dependent diabetics at risk.

Submersion and Directed Flow Cooling Technology for Military Applications

As the US military shifts from boots on the ground to drones in the sky, there will be an increasing need for computing power on foreign soil, under the sea and in the air. Design objectives will be difficult to achieve with legacy technology. Electronic gear must be deployed by transport plane and require rapid setup once the destination is reached. Systems will need to be hardened to survive extreme temperatures, desert sand, salt air and pollution. Fuel logistics to serve remote locations can be difficult and expensive. Every kilowatt-hour of electricity converted to heat must be dissipated and, ideally, the waste energy should be recycled. For ground installations, it will be useful to consider distributing computing resources around rather than concentrating them at a single location that may be vulnerable to attack. Silent operation also is desirable.

Avionics Heat Up, in a Good Way

The common feature shared by recent aviation platforms is the high level of systems integration, and the way in which information is displayed or made accessible, allowing previously unimaginable levels of situational awareness to be available to pilots and ground controllers. This has greatly eased the pilot workload and enhanced flight safety, especially when flying in poor weather or operating in unfamiliar or hazardous terrain.

Airborne Antenna Considerations for C-Band Telemetry Systems

It is fairly well known within the aerospace community that telemetry is moving from the traditional L-band and S-band frequency ranges up to C-band. It is widely understood that the reason for this push to C-band is two-fold. First, traditional L and S frequency bands have been greatly reduced through reallocation for a variety of reasons by different markets, and second, the bandwidth required for most applications has seen exponential growth. This has not only been seen in military applications, but in civilian aerospace platforms as well.

Developing and Validating Statistical Cyber Defenses

Enterprise business processes are more connected than ever before, driven by the ability to share the right information with the right partners at the right time. While this interconnectedness and situational awareness is crucial to success, it also opens the possibility for misuse of the same capabilities by sophisticated adversaries to spread attacks and corrupt critical, sensitive information. This is particularly true for an insider threat scenario in which adversaries have legitimate access to some resources and unauthorized access to other resources that is not directly controlled by a fine-grained policy.

Next-Generation Spectrometers for Rapid Analysis of Complex Mixtures

Molecules have internal motions that are characteristic of their structure and identity. These motions can be studied by spectroscopy in different regions of the electromagnetic spectrum. Molecular spectra can be used as a “fingerprint” to unambiguously state whether or not a particular chemical is present and in what amount. As such, small portable spectrometers are frequently used as components of chemical sensors.

Wireless Vital Signs Monitor for Trauma Patients

A miniature, portable wireless vital signs monitor (MWVSM), called Mini-medic™, could aid in the triage and diagnosis of trauma patients with and without traumatic brain injury (TBI). The MWVSM consists of two components, both of which are the approximate size and weight of a cellphone: one is a sensor that is placed either on the forehead or the fingertip of a patient, and the other is a monitor that receives a wireless signal transmitted up to 100 m carried by the medic.
