Moccia ___________________________________________________________________________ Francesco De Rosa - Electrically Heated Composite Leading Edges for Aircraft Anti-Icing Applications 2 Abstract An investigation was conducted in the Aerospace Engineering Department (DIAS) at Federico II University of Naples aiming to evaluate the feasibility and the performance of an electrically heated composite leading edge for anti-icing and de-icing applications. A 283 [mm] chord NACA0012 airfoil prototype was designed, manufactured and equipped with an High Temperature composite leading edge with embedded Ni-Cr heating element. The heating element was fed by a DC power supply unit and the average power densities supplied to the leading edge were ranging 1.0 to 30.0 [kW m-2]. The present investigation focused on thermal tests experimentally performed under fixed icing conditions with zero AOA, Mach=0.2, total temperature of -20 [°C], liquid water content LWC=0.6 [g m-3] and average mean volume droplet diameter MVD=35 [µm]. These fixed conditions represented the top icing performance of the Icing Flow Facility (IFF) available at DIAS and therefore it has represented the “sizing design case” for the tested prototype.

The movements of flight controls are converted to electronic signals transmitted by wires (hence the fly-by-wire term), and flight control computers determine how to move the actuators at each control surface to provide the ordered response. The fly-by-wire system also allows automatic signals sent by the aircraft's computers to perform functions without the pilot's input, as in systems that automatically help stabilize the aircraft.[1] Contents Green colored flight control wiring of a test aircraft 1 Development 1.1 Basic operation 1.1.1 Command 1.1.2 Automatic Stability Systems 1.2 Safety and redundancy 1.3 Weight saving 1.4 History 2 Analog systems 3 Digital systems 3.1 Applications 3.2 Legislation 3.3 Redundancy 3.4 Airbus/Boeing 4 Engine digital control 5 Further developments 5.1 Fly-by-optics 5.2 Power-by-wire 5.3 Fly-by-wireless 5.4 Intelligent Flight Control System 6 See also 7 References 8 External links Development http://en.wikipedia.org/wiki/Fly-by-wire Page 1 of 9 Fly-by-wire - Wikipedia, the free encyclopedia 11-8-20 下午5:33 Mechanical and hydro-mechanical flight control systems are relatively heavy and require careful routing of flight control cables through the aircraft by systems of pulleys, cranks, tension cables and hydraulic pipes.
  • Aircraft Winglet Design

    Aircraft Winglet Design

    DEGREE PROJECT IN VEHICLE ENGINEERING, SECOND CYCLE, 15 CREDITS STOCKHOLM, SWEDEN 2020 Aircraft Winglet Design Increasing the aerodynamic efficiency of a wing HANLIN GONGZHANG ERIC AXTELIUS KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ENGINEERING SCIENCES 1 Abstract Aerodynamic drag can be decreased with respect to a wing’s geometry, and wingtip devices, so called winglets, play a vital role in wing design. The focus has been laid on studying the lift and drag forces generated by merging various winglet designs with a constrained aircraft wing. By using computational fluid dynamic (CFD) simulations alongside wind tunnel testing of scaled down 3D-printed models, one can evaluate such forces and determine each respective winglet’s contribution to the total lift and drag forces of the wing. At last, the efficiency of the wing was furtherly determined by evaluating its lift-to-drag ratios with the obtained lift and drag forces. The result from this study showed that the overall efficiency of the wing varied depending on the winglet design, with some designs noticeable more efficient than others according to the CFD-simulations. The shark fin-alike winglet was overall the most efficient design, followed shortly by the famous blended design found in many mid-sized airliners. The worst performing designs were surprisingly the fenced and spiroid designs, which had efficiencies on par with the wing without winglet. 2 Content Abstract 2 Introduction 4 Background 4 1.2 Purpose and structure of the thesis 4 1.3 Literature review 4 Method 9 2.1 Modelling

  • 6 Fuselage Design

    6 Fuselage Design

    6 - 1 6 Fuselage design In conventional aircraft the fuselage serves to accommodate the payload. The wings are used to store fuel and are therefore not available to accommodate the payload. The payload of civil aircraft can consist of passengers, baggage and cargo. The passengers are accommodated in the cabin and the cargo in the cargo compartment. Large items of baggage are also stored in the cargo compartment, whereas smaller items are taken into the cabin as carry-on baggage and stowed away in overhead stowage compartments above the seats. The cockpit and key aircraft systems are also located in the fuselage. 6.1 Fuselage cross-section and cargo compartment Today’s passenger aircraft have a constant fuselage cross-section in the central section. This design reduces the production costs (same frames; simply instead of doubly curved surfaces, i.e. a sheet of metal can be unwound over the fuselage) and makes it possible to construct aircraft variants with a lengthened or shortened fuselage. In this section we are going to examine the cross-section of this central fuselage section. In order to accommodate a specific number of passengers, the fuselage can be long and narrow or, conversely, short and wide. As the fuselage contributes approximately 25% to 50 % of an aircraft's total drag, it is especially important to ensure that it has a low-drag shape. A fuselage 1 fineness ratio ldFF/ of approximately 6 provides the smallest tube drag . However, as a longer fuselage leads to a longer tail lever arm, and therefore to smaller empennages and lower tail drag, a fineness ratio of 8 is seen as the ideal according to [ROSKAM III].

  • Fuselage Design Okay, Right, We Want to Build an Airplane, We Need to Design a Fuselage

    Fuselage Design Okay, Right, We Want to Build an Airplane, We Need to Design a Fuselage

    (simplified) Fuselage design Okay, right, we want to build an airplane, we need to design a fuselage. The following text is a short tutorial that will take you all along on what needs to be considered when designing such structure. 1 It is highly important to know all requirements the airplane will need to be fulfilled. You must know what you are building your airplane for. You MUST. Once you have done that, and already did the firrst important calculations, you can start designing the fuselage. In subsonic airplanes, it’s usually the payload that drives the design. Another rule of thumb is that the design is built from the inside out (see picture below as example): 2 Of course, the larger the fuselage, the more payload you can take, and this at a higher comfort. However, a smaller fuselage will also mean less drag. Remember! Even though payload is the driving factor, you are still interested in other requirements such as range. The exact diameter and length of the fuselage will be our first dilemma, since it causes 20 ­ 40% of the total zero drag coefficient. An increase of 10% in the diameter yields a 2% in drag increase. Nevertheless, many aircraft companies focus on building a fuselage, whose design allows flexibility. What do I mean with it? Well, it includes various types of flexibilities: ­ Usually the cross section in an aircraft, once set, remains fixed. However the length remains as a changing variable, which results in a higher number of aircrafts just like shown below with the A380.
