Getting Along at the Major Terminals - General Aviation and the Airlines

Achievement of this goal is dependent on adequate planning efforts, based on accurate forecasts of total traffic and a breakdown of the total into three segments: Airline and Heavy Jet, Light Jet and High Performance Piston, and Light Single Engine. A natural segregation of these three types of traffic will be accomplished by the provision of different types of airports designed to serve the needs of each user group.

NASA's Fundamental Aeronautics Subsonic Fixed Wing Project: Generation N+3 Technology Portfolio

Success in overcoming these technical challenges will result in major changes to engine cycle and airframe configurations that will in turn broaden the technology trade space for a variety of subsonic vehicle sizes ranging from large transports to very light jets. These new capabilities will enable the national vision of significant growth in airspace system throughput in coming decades while reducing overall environmental impact.

A New Surface Coating for Prevention of Icing on Airfoils

New icephobic paint has been developed for the purpose of preventing the icing of the airfoils of aircrafts. The basic characteristics of the paint in terms of icing prevention were examined by an optical method and a load test. The water contact angle is so high-150 degrees-that high water repellency can be obtained as expected from the design. The adhesion strength of the ice formed on this coating is decreased to the lowest value as compared to all paints ever developed. The results from the icing wind tunnel test carried out in conditions similar to what aircrafts encounter show that the paint contributes to fuel and weight savings due to the effective use of deicer.

An Electro - Mechanical Actuator for General Aviation Aircraft

The Institute of Aircraft Systems at the University of Stuttgart, Germany is developing an Easy Control System (ECS), with the primary goal to make General Aviation aircraft capable to cover the needs of future individual traffic. Objectives of the ECS are a significant reduction of pilot workload, an increase in safety and an increase in aircraft performance by providing all-time easy and safe handling qualities with advanced control and protection functions. Due to the focus of applicability in General Aviation aircraft and corresponding certification efforts the ECS requires the development of a highly integrated, absolutely safety critical, all-electric full fly-by-wire platform with low risk investment capability for both supplier and customer. One of the primary elements of this platform is an electro-mechanical actuator driving the aerodynamic control surfaces of the aircraft.

Nozzle Flow and Spray Development One-Way Coupling Methodology for a Multi-Hole GDi Injector

The use of predictive models in the study of Internal Combustion Engines (ICE) allows reducing developing cost and times. However, those models are challenging due to the complex and multi-phase phenomena occurring in the combustion chamber, but also because of the different spatial and temporal scales in different components of the injection systems. This work presents a methodology to accurately simulate the spray by Discrete Droplet Models (DDM) without experimentally measuring the injector mass flow rate and/or momentum flux. Transient nozzle flow simulations are used instead to define the injection conditions of the spray model. The methodology is applied to a multi-hole Gasoline Direct injection (GDi) injector. Firstly, the DDM constant values are calibrated comparing simulation results to Diffused Back-light Illumination (DBI) experimental technique results. Secondly, transient nozzle flow simulations are carried out.
