JUNE 2019 I DESIGN007 MAGAZINE 27 liability, and I still think they sell themselves short in a way. Gaines: Sometimes, designers look at board shop specifications of what they can do, not that the board needs that tight of geometry, but they can do it, so that's what they put on the circuit board. Some eight-layer boards that could easily be reduced to six-layer boards, or 14 reduced to 10. Just look at it, decide what you need, and don't think, "I'm just trying to do a board and get it off my desk." Shaughnessy: Because everybody's rushed. Gaines: In this world, if you're not rushed, then you're probably not needed (laughs). Shaughnessy: What advice would you give to a new designer on how to take control and be aware that they can help make the product profitable? Gaines: Look at a broad spectrum of standards of what's required for different designs. Tech- nologies will drive what you're going to have to do with space and clearance, but don't put yourself in a corner. Be open to other people's opinions because one supplier on this product may ask for something while another suppli- er may ask for something completely different. You need to be understanding and ask ques- tions. Make a list of what you need for the next time you're going back through it again. I have default output files that I call up with everything; all I have to do is change a file name, click a button, and it outputs every- thing. I don't care if it's a board with four parts on it or one that has thousands. They all out- put the same pack of data. I send everybody that data, and if they choose not to use half of it, that's fine. I won't get a call back, saying, "Please send me this." Too much data is prob- ably the right amount. Shaughnessy: That's good. Thanks, Albert. Gaines: Thank you, Andy. Good to see you. DESIGN007 KLM Partners With TU Delft to Make Aviation More Sustainable KLM President and CEO Pieter Elbers and Dean of the Faculty of Aerospace Engineering at Delft Uni- versity of Technology (TU Delft) Professor Henri Wer- ij have signed a new cooperative agreement to work together on making aviation more sustainable at the IATA Annual General Meeting in Seoul. KLM will be contributing towards TU Delft's re- search into an innovative flight concept known as the "Flying-V," which embraces an entirely different ap- proach to aircraft design, in anticipation and support of sustainable long-distance flight in the future. Although the plane is not as long as the A350, it does have the same wingspan. This will enable the Flying-V to use existing infrastructure at airports, such as gates and runways, without difficulty and the aircraft will also fit into the same hangar as the A350. What's more, the Flying-V will carry the same number of passengers—314 in the standard configuration—and the same volume of cargo, 160m 3 . The aircraft's v-shaped design will integrate the passenger cabin, the cargo hold and the fuel tanks in the wings. Its improved aerodynamic shape and re- duced weight will mean it uses 20% less fuel than the Airbus A350, today's most advanced aircraft. The Flying-V is propelled by the most fuel-effi- cient turbofan engines that currently exist. In its present design, it still flies on kerosene, but it can easily be adapted to make use of innovations in the propulsion system—by using electrically-boosted turbofans, for example.
