Volvo rolls into research
-
Prof. Bengt-Olof Elfstrom, Project Leader of Volvo Aero's research effort for the European Union's Fifth Framework Program, envisages many design and engineering challenges for aircraft producers in the new century, including the development of fuel cells to meet enhanced electric power demands for onboard systems. He also sees a move toward greater modularity - much as there has been in the auto industry - and away from individual components. "I believe there will be more of a systems approach," he said. "Also, in 10 years we will be able to simulate everything we do in the workshop - and the things we can't simulate we won't produce. The key to success will be the skilled individuals who can handle IT."
Volvo Aero is involved in seven different research projects, as well as a demonstrator project concerning aircraft engines, within the Fifth Framework Program. The aim of the demonstrator project is to develop effective, environmentally compatible aircraft engines. The targets are to reduce development costs by 20%, lead times by 15%, and component costs by 20%. Success will bring added bonuses including more effective, more environmentally compatible aircraft engines, and more reliable components.
The project has two aspects. The first, which is being led by MTU and Snecma, will produce a demonstrator for the technology that will be used in the next generation of aircraft engines. Volvo Aero is responsible for developing a low-pressure turbine case and turbine exhaust case. The other project is being managed by Rolls-Royce and will demonstrate a more conventional aircraft engine with technology that will be included in production within five to seven years. Volvo Aero has the task of developing a turbine bearing housing. Both demonstrators are scheduled for completion in 2003.
