The objective of this paper is to design and analyze a UAV fuselage. Our design with 45lb maximum loading had 283.16ft of ground run distance. 1 September 1991. It's about design SPAD aircraft, but there is a LOT of good info there regarding sizing the wing, fuselage and tail feathers. The design of the fuselage is based on payload requirements, aerodynamics, and structures. Then, the internal system installation, cargo positioning and fuselage structure are designed. Initial Buckling Calculations With frame positions determined by attachment points of the wing spar, seats, main undercarriage and BRS then the panel lengths for the fuselage skin buckling analysis could be established. d design i iteration number s slicing plane 0, 1 0th and 1st iteration, respectively Procedure and Sample Calculations General Considerations For this investigation, the general approach is to gradually, by iteration, correct the fuselage shape to yield the desired effective area distribution, using a known analysis method. The fuselage diameter is 2280 mm and the distance between frames is 432 mm. made to the fuselage because buckling is in the most cases the most critical condition to the fuselage. 3.1 Project Design Overview 3.2 Designing the UAV 3.3 Fabrication of UAV Fuselage 23 25 26 4 DESINING AND MANUFACTURING THE UNMANNED AERIAL VEHIVLE 27 4.1 Designing the UAV 4.1.1 Fuselage Design 4.1.2 Empennage 4.1.2.1 Single Boom or Double Boom 4.1.2.2 Empennage Design 4.2 Material Selection 4.2.1 Fuselage Material 4.2.1.1 Fuselage Frame It focuses on aircraft turnaround as design driver for fuselage design decisions. The overall dimensions of the fuselage affect the drag through several factors. Mizanur Rahman. Views 225. The result of iterative calculations is an optimized design regarding weight, costs and aircraft performance. Another approach to the panel problem is given in Shanley. fuselage design and explained in the following sub-sections. This work investigates fuselage design in the short and medium range segment for passenger aircraft. The design moment and shear load of the fuselage are My = 1.03 × 10 6 Nm and the S = 168050 N, respectively. Stephen Tytler. at the intersection. Progress in Finite-Volume Calculations for Wing-Fuselage Combinations. AIRFRAME STRUCTURAL DESIGN COURSE CODE:A72118 IV B. Student. uav fuselage design and structu ral analysis Adnan Shahriar a , Md. Fuselages with smaller fineness ratios have less wetted area to enclose a given volume, but … All the fun and features of solitaire. Description. The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft. Hobbes' reply has some of the main reasons, but there's some more: That flat bit is called the "belly fairing", and its functions are: Avoid some aerodynamically awkward corners that would happen if the wing profile just went straight through the fuselage, with no rounded corners etc. Adnan Shahriar. (2) Focusing on the complicated calculations of the additional generalized aerodynamic forces, we use 1-order complex response surface of it to simplify the optimization process, and enhance the optimization efficiency. Static duct network design and simulation, simply drag and drop to model duct system in very short time. In single-engine aircraft, it will usually contain an engine, as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull . However, where any discrepancies occur between these calculations and the working drawings, the Engineer shall be notified immediately so proper action may be taken. a, Md. ... For our calculation, the fuselage fineness ratio is about 4.8 and the form factor is about 1.55.
