Evaluation of Aeronautical Design Standard – 33 Using a UH-60A Black Hawk

In 1982, the U.S. Army Aeroflightdynamics Directorate (AFDD), then assigned under the U.S. Army Aviation Systems Command (AVSCOM), began development of a new handling qualities specification for military rotorcraft. This effort resulted in the U.S. Army's initial Aeronautical Design Standard–33 (ADS-33A), “Handling Qualities Requirements for Military Rotorcraft,” published in May 1987. It was initially applied to the RAH-66 Comanche Helicopter program, meaning the handling qualities requirements generally related more to scout and attack classes of rotorcraft. As more data became available and lessons learned emerged from using ADS-33A, refinements were implemented into ADS-33B and ADS-33C).

The United States Air Force's (USAF) activities to establish air superiority and support ground combat units often require the use of secure airfields in remote and challenging areas. Thales Deployable – Instrument Landing System (D-ILS), a compact and movable variant of the standard ILS, can help them accomplish this mission.

Circuit Models for Robust, Adaptive Neural Control

This project seeks to reproduce the neural circuits used by the nematode Caenorhabditis elegans for locomotion. Caenorhabditis elegans is a small (~1.2 millimeter) nematode found in rotting fruit in many parts of the world. It feeds on bacteria and is neither parasitic nor pathogenic. Although capable of sexual reproduction, most laboratory strains reproduce primarily as self-fertilizing hermaphrodites, with each adult hermaphrodite producing approximately 300 progeny (Figure 1).

An Introduction to PCM Heat Sinks

With the exception of thermal storage heat sinks, the term heat sink is a misnomer. Standard heat sinks for electronics cooling are actually heat exchangers, taking the heat from the electronics, and transferring it to a fluid, either air or coolant. Phase Change Material (PCM) heat sinks are the only heat sinks that actually act as a (temporary) sink for heat. They are emerging in the thermal management realm to solve thermal problems in systems where active solutions cannot be used. When there is no place to dissipate the heat generated by electric components, a PCM heat sink is capable of absorbing the generated waste heat [1] .

Pulsed Microwave Plasma Instrumentation for Investigation of Plasma-Tuned Multiphase Combustion

Strategies to control solid rocket propellant regression rate require a robust throttling technique applicable to high performance propellant formulations. Currently, several methods to control and throttle either motors or subscale propellant strands exist, including chamber pressure control (e.g. pintle nozzles or rapid depressurization quench), infrared laser irradiation of the burning surface to increase burning rates, development of inherently unstable combustion chamber geometries (producing either local pressure or velocity perturbations), and electrically sensitive hydroxylammonium nitrate (HAN)-based formulations in which burning rate is controlled by a voltage potential. However, these techniques are limited in that they either can only be used with low flame temperature (low specific impulse) propellants, result in low propulsion system mass fraction (pintle), are only capable of producing a single perturbation, or are formulation specific.

Eye Tracking Technology

Much debate surrounds the skills shortage burdening the manufacturing sector of aerospace and defense (A&D). Industry 4.0, the Baby Boomer retirement wave, and a lack of properly trained workers underpins this issue, and while it's widely acknowledged, there's no clearly defined way to address it.

Novel Characterization Methods for Anisotropic and Mixed-Conduction Materials

State-of-the-art electronic and optoelectronic devices require electronic materials with specialized properties that cannot be characterized with standard methods, or that must be characterized with extra precision. As a result of this research, the following new materials characterization methods have been developed:

Using RISC-V to Simplify Data Logging in Space

Worldwide demand for low Earth orbit satellites is increasing at an unprecedented pace, driven by diverse needs such as faster and more affordable Internet access, and faster revisit rates with finer resolution for imaging data. The satellite payload instruments performing communications or imaging functions are becoming increasingly sophisticated and capable and require the collection of increasing amounts of telemetry data to ensure the safe and reliable operation of the satellite.
