The Development of Very Light Jet with Unconventional Arrangement
In order to be economically viable and competitive, the current trends in designing very light jet aircraft have shown that it is essential to improve the aircraft performance and operational flexibility goal, nevertheless have an efficient cost. The application of unconventional configuration has attracted the designer to achieve that goal. This paper discusses the prospective design of unconventional arrangement which will be applied for very light jet aircraft. The existing of a very light jet configurations is reviewed. New concepts of unconventional configuration for this type of aircraft are discussed. The three-surface configuration is then proposed for the design project. The configuration offers stability and unobstructed cabin. With the appropriate design, the additional weight and interference drag due to the extra surface can be reduced. The new design of aircraft configuration and cabin are discussed. High Speed Natural Laminar Flow airfoil is applied to obtain High Lift/Drag Wing design. The weight and aircraft performances are then estimated. The predicted aircraft performance has satisfied the design requirements and objectives. The design process covered by this paper is only concentrate on initial design. The data from this paper can be continuing in future for the next step of design.
