Magnetics Design: Specification, Performance & Economics

An informative white paper from Datatronics Romoland, Inc., provides a discussion of the design, development and delivery of affordable magnetic components. The design development process begins once performance requirements are specified. Upon design approval, the procurement of materials for a prototype build is initiated. During this stage, specifications are not final and options remain open for cost-effective production. Specifications must be reviewed and design trade-offs evaluated to ensure that the technical requirements are economically attainable with consideration given to performance and tolerance in relation to affordable cost.

Two-Stroke Engines

Ewatt AeroSpace Company (Wuhan, China) has developed a new series of lightweight, powerful and reliable two-stroke engines for both UAV and light-manned aircraft. The engines are being designed and developed by aircraft engine designer Guido Polidoro in Ewatt’s new European Engine Development Center in Piacenza Italy. The new Ewatt engine is designed to be modular, and expandable into multi-cylinder versions to produce more horsepower. Each cylinder has 188cc displacement, developing 22 horsepower at 7500 RPM, making the single-cylinder version, at 7 kilograms, a powerful alternative to other engines on the market.

Propulsion Performance Model for Efficient Supersonic Aircraft

For the design process of the class of aircraft known as an efficient supersonic air vehicle (ESAV), particular attention must be paid to the propulsion system design as a whole including installation effects integrated into a vehicle performance model. The propulsion system assumed for an ESAV considered in a recent study done by Optimal Flight Sciences LLC and the Air Force Research Laboratory was a three-stream variable cycle engine (VCE).
