Maintainers design a $400 maintenance fixture to save the U.S. Air Force $500k per year

2019-04-30
A cowling, or engine cover, is a critical airframe component that reduces drag and directing airflow into the engine. For the E-8C JSTARS, an aircraft with four massive Pratt and Whitney JT3D-based TF33-102C turbofan engines, each set of engine cowling components can cost up to $80,000 per set. Even a slightly warped cowling renders the entire housing unsafe and unserviceable.

FAA, SAE International focus on engine fire protection system standards for aerospace

2018-06-18
Aerospace systems, subsystems, and components must continue to operate as intended when exposed to fire, rather than going up in flames and ceasing to work altogether. Fire and flammability testing is an all-important prerequisite to airworthiness, and the focus of a new technical standards committee that SAE International in Warrendale, Pennsylvania, is forming in response to a request from Federal Aviation Administration (FAA) officials in Washington.

Designing composite engine cowling for improved heat resistance

2018-02-05
Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.

GKN Aerospace to develop first additive-manufactured rocket engine turbines in Europe for Prometheus project

2018-09-05
GKN Aerospace in Trollhättan, Sweden, are developing and manufacturing the first additive-manufactured, or 3D-printed, rocket engine turbines in Europe, officials say. The tier 1 aerospace supplier is harnessing cutting-edge additive manufacturing (AM) technology to produce two full-scale turbines for the Prometheus reusable rocket engine demonstrator on liquid oxygen and methane propellants, while reducing the number of parts from more than 100 to 2 and cutting costs by 90 percent.
