    Abstract:- This paper intends to present the conceptual design of very light jet (VLJ) aircraft in the university level. The design process that covers by this paper is just from conceptual approach. Current technical information of the business jet in the market will be studied for competitor analysis purpose. After that, the calculation process will take part, like initial sizing, performance sizing, initial sizing of main component, weight breakdown, cg (centre of gravity) position and aircraft performance. This paper will only concentrate on conceptual design, the next stage of design can be continuing in future with the data from this paper. Key-Words:- conceptual design, wing design, aircraft design, aerodynamic configuration, light jet 1

    Non-linear finite element code ABAQUS/Explicit was employed to evaluate the energy absorption characteristics of concentric circular tubes subjected to impact in the axial direction. Thin-walled circular tube plays a vital role as energy absorber due to its high energy absorption capacity. However, the main drawback of existing tube type energy absorber is the high initial peak load. This work evaluates

    The use of nanocoolant is suspected to have effects on erosion-corrosion of piping systems in heat exchanger. This study was carried out to determine the erosion corrosion of AISI 316 stainless steel in solutions containing nanoparticles. The experiments used rotating cylinder electrode (RCE) at rotational speed of 0-1800 rpm under varying temperature of 30oC-70oC. Corrosion rate was measured using linear polarization resistance (LPR) method and erosion was indicated by measuring average depth of surface of the samples (surface roughness). The results showed that both corrosion rate and surface roughness of samples have increased when temperature and rotation speed increased. The erosion-corrosion effects of nanocoolant were lower in stagnant condition. Comparing with conventional coolant, the nanofluid showed significant differences. In flow conditions, the effects were remarkable. It was also found that maximum synergism erosion and corrosion were occurred at higher temperature an...

    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 Lif...
