A multi-role very light jet (VLJ), the Stratos 716 is designed to seat six and support personal, business, and air taxi use.

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.

The reliability design review as a highly disciplined, organized approach to failure mode/failure consequence studies is reappraised in light of jet engine design and development experience. Reliability design prediction techniques based on two approaches are described. 1.

Plain talk from plane engineers Two companies with different backgrounds focus on different technologies in bringing to market new very light jets.

VLJ power Some engine programs for very light jets are full swing while certification awaits others.

Very Light Jets (VLJ)1 could very well revolutionize regional air travel around the world for both business and pleasure by providing an affordable alternative for thousands of owner/pilots, small companies, and potential customers of on-demand air services.

The demands for light jets have been increasing and new developments are rising to supply this market. The major concern in the development of a new aircraft is the customer satisfaction.

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.

An icy reception Next-generation propulsion systems for next-generation aircraft still have to address an (ice) age old problem.

Designing high-bypass nacelle inlets Simulation significantly reduces the time required of engineers at Goodrich to evaluate inlet performance and preliminary designs. Virtually eliminating prototypes IBM PLM Solutions developed by Dassault Systemes have enabled Dassault Aviation to meet the challenges of the executive business jet market with a new virtual platform. DOD looking for faster fixes The U.S. military is in the midst of a mighty push at its bases and depots to shorten the time it takes to get aircraft, trucks, tanks, and other weapon systems out the gate after they arrive for repair. A vision of military and civilian aviation tomorrow SAE 100 Future look: At Dessault Aviation, we believe the quest to fly "higher, faster, and further" that moved moved aviation's pioneers will continue to blaze new trails in the 21st century.

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.

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.

Budgeting for the future Rolls-Royce spends more than $3 million a day-$1.1 billion a year- on research and development. Top technologies of the year A look back at some of the most significant technological innovations in the news during the past year.

Managing positioning integrity Thales has established a new reference system to comply with the most demanding RNP-AR navigation procedures. Business jets wait for the uplift A look at how the global executive jet market is fighting back after a hard few years.

Dassault-business aviation pioneer More than four decades of design and engineering evolution have seen the French business jet producer create a wide range of twin-and tri-jet Falcons, from the 20 to the latest 7X. Maintaining reliability Regional airlines and business jet operators care about fuel efficiency, just not as much as engine reliability. Introducing Greg Henderson, SAE President for 2006 The Lockheed Martin executive steps up to take SAE into its next 100 years.

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.
