Managing the Impact of Nanomaterials in Aerospace Manufacturing

As the aerospace industry continues to make improvements to safety, comfort and affordability of aircraft, nanomaterials are making their way into more elements of aircraft structure, electronics, glass, textiles and other components. While these materials provide tangible advantages in terms of weight, strength, speed and comfort, their effect on the humans that come into contact with them is still being studied and debated.

Turbine Flow Meters: Technology-of-Choice for Measuring Critical Fluid Flow Applications

The aerospace industry has some of the most difficult operating conditions imaginable. Sensors of all kinds used in this industry must stand up to the environment and be able to perform under harsh conditions, fit in extremely tight spaces, and have electronics that can compensate for variable conditions in order to provide precise, repeatable results.

Designing a Power Generation System for a More-Electric Aircraft

It is theorized that systems and equipment for an All Electric Aircraft (AEA) will be developed 20 years hence as a More-Electric Aircraft (MEA) with no bleed system, which is a concept typified by the Boeing 787, and electric powered propulsion (including electric distributed thrust or electric hybrids by gas turbine power generation), which is expected to be realized after the 2040s. In this trend, a More-Electric Engine (MEE) plays the roles shown in Table 1.

Developing an Auto-Synchronized Multi-Avionics Protocol Data Bus Acquisition System

A modern aircraft includes multiple intelligent subsystems that aid in communication, navigation, and surveillance. These subsystems, called line replaceable units (LRUs), are modular and easy to replace in the field. Typically, independent teams design and develop LRUs. It is important to test the LRUs with a test rig on the ground before integrating them on the aircraft. A ground-based LRU integration rig (LRUIR) facility uses state-of-the-art hardware and software in a distributed architecture to help completely integrate the process of verifying the functionality of the avionics subsystems. An LRUIR provides a platform to test the LRUs in an integrated environment on the ground.

Night Vision Displays

Daisy Data Displays
York Haven, PA

United States Coast Guard officials required night-vision goggle compatibility for the flat panel display systems used in the Lockheed C-130 military aircrafts. To meet the requirement, they recently purchased Fleetmate 7171CA Series thin client flat panel displays with night-vision technology manufactured by Daisy Data Displays.

Fuel Flow Meters

Hoffer Flow Controls
Elizabeth City, NC

Hoffer Flow Controls, Inc. recently received a new contract to supply 575 fuel flow meters as a part of the U.S. Navy’s H-53 heavy lift helicopter fleet upgrade. The most powerful helicopter in the U.S. Military, H-53 helicopters perform many tasks within the U.S. Military including heavy lifting, transport of supplies, combat search, rescue missions and mine sweeping to clear vital shipping lanes. The current H-53 helicopter fleet is slated to remain in service until mid-to-late 2020’s.

Creating Simulated LIDAR Images of Human Poses in a Virtual Laboratory

LIDAR is a partial 3D standoff sensing method that illuminates a target with rotatory or flash laser beams, analyzes the reflected lights, and provides both the distance to the target’s surface and the target’s surface shape. An array of laser reflections can be used to map the facing-side surface of a target object as a partial point cloud. Unlike a 360° surface model generated by a traditional full body scanner, the partial point cloud from a LIDAR is a viewing angle dependent 3D representation of the target shape. The resolution of these maps depends on the density of the laser detector array; a good image of a human may require hundreds of detection pixels to capture enough detail to clearly detect changes in limb positions.
