Rear Fuselage and Empennage Flow Investigation (REMFI)

Objective

It is known that business needs are placing an ever-increasing demand on the aeronautics industry to develop and manufacture aircraft at lower costs, with improved flight capabilities and a reduced impact on the environment. Hence, a primary objective for the aerospace industry is to offer products that not only meet the operating criteria but also significantly reduce the direct operating costs. Furthermore, research effort with respect to an improved understanding of the flow physics around fuselage / tail combinations remained limited, as investigations naturally concentrated on the wing and its interaction with the fuselage. However, a successful design approach towards the development of modern transport aircraft has to take the empennage as well. Thus, the improvements to be achieved by REMFI focus on three main aspects, the enhanced understanding of the tail flow physics, improved computational predictions for fuselage/tail design and analysis and improved experimental capabilities and measuring techniques for tail flows. This aims at providing means to: - Increase the empennage aerodynamic efficiency and reduce loads - Improve flight safety - improved empennage performance and weight for optimised gaps effects, including Reynolds number effects - Investigate sting mounting arrangement effects on empennage wind tunnel measurements - Enhance the current scaling methodologies to free-flight conditions - Reduce fuel burn (this has a positive effect on energy saving and reduction of emissions to the environment) - Novel design concepts for integrated fuselage / empennage designs with significant interaction between rear fuselage and belly fairing - Investigate novel flow control devices (speed brakes) on fuselage and vertical tail - Shorten the design cycle - Reduce the cost of the aerodynamic design of tail and fuselage - Reduce the maintenance costs
