Puncture-Healing Thermoplastic Resin Carbon-Fiber Reinforced Composites

This technology self-repairs following low- to mid-velocity impacts. A through-transmission C-scan of the healable composite panel shows the material post-impact (top) and post-healing cycle (bottom). NASA’s Langley Research Center has developed carbon fiber reinforced composites with self-healing properties. The initiation and propagation of damage to carbon composites, such as in aircraft structural components, results in component failure. Typical structural repairs result in damaging practices, where material is ground away and holes are drilled to secure patches, which can act as new sites for damage. This technology exhibits effective self-repair that heals quickly following low- to mid-velocity impacts, while retaining structural integrity.

Optimum Strategies for Selecting Descent Flight-Path Angles

Efficient and safe arrival operations under challenging traffic conditions are a key objective for air transportation modernization efforts taking place throughout the world. However, trajectory predictability issues often prevent Air Traffic Control (ATC) from allowing continuous descent approaches in congested airspace. An arrival procedure with a specific descent profile, such as a fixed-flight-path angle, provides high trajectory predictability for air-traffic management. Accordingly, it can enable ATC to increase the use of continuous descent approaches, thereby increasing the throughput of arrival operations and reducing fuel burn and other direct operating costs in the process. Moreover, such a procedure is already supported by current avionics in almost all small (regional, business, and light) jets and a fraction of large jets, including Boeing and Airbus.

Active Aircraft Pylon Noise Control System

This technology can be used in commercial aircraft, business jets, and UAVs.This technology is a new type of aircraft pylon design for noise control. A pylon connects the engine to the airframe of an aircraft. This design uses air passing through the pylon to actively disrupt the jet engine exhaust stream after it exits the engine, disrupting and redistributing the axial and azimuthal distributed sources of jet noise from the aircraft.

Common Workflow Service: A Standards-Based Process Management System

As mission operations grow in scale and complexity, there is a prevailing need for automating operational processes to increase efficiency, mitigate risks, and reduce operational costs. The need for automating operational processes has produced a few disparate automation systems within the Advanced Multi Mission Operations System (AMMOS). Without a common solution for process management and automation, each AMMOS subsystem that requires a workflow capability will need to develop its own expertise in the workflow domain as independent systems are developed. This can lead to many incompatible implementations that functionally do similar things. The Common Workflow Service (CWS) attempts to address this issue to avoid independent ad hoc workflow implementations.
