A: An aircraft flying steady and level at true airspeed of 720 km/hr at sea level. The aircraft have two engine at 85.4kN thrust each and drag polar equation is CD-0.035+0.05 CL2, wing area is S-187m². What is aircraft weight? Cal. na?
An ongoing research to investigate the unsteady aerodynamics of insect flight is being conducted at the Fluid Mechanics Laboratory in NUS; the outcomes of which are important in the development Flapping Micro-Air-Vehicles. As part of this research, an experiment has been conducted on a simplified two-dimensional elliptic wing to study the effect of sinusoidal heaving (i.e. moving up and down) and pitching (1.e. oscillating) motion of the wing on the generation of propulsion force. The wing has a chord length (distance between the leading and trailing edge of the wing) of c, and is pitching about the mid-chord (i.e. c/2 from the leading edge) as shown in Figure 3(a). The thrust or propulsive force of the wing (I) is expected to be a function of free stream velocity (U), chord length (c), frequency of heaving (f), amplitude of heaving (A), frequency of pitching (2), angular amplitude of pitching (a), density of fluid (p) and dynamic viscosity (u). Rewrite this relation in non-dimensional…
Expanded.4 deals with the conservation of momentum principle. Using the conservation of momentum principle to solve this problem is mandatory. Solution using other approaches will be automatically considered false. For the problem related to Expanded.4, sketches of the system showing: • the respective initial and final velocity and position coordinates and the frame of reference considered • the forces acting on the system of considered, in other words, a free body diagram (FBD) are mandatory. Their absences will automatically make the problem false. A B F 300 mm 600 mm Knowing the angular velocity of rotation of the bob, 4-kg, is 3 rad/s when the length of the rope is 600mm and the angle is 44°, what is the angular velocity of the rope if the length of the rope becomes 300mm while the angle reduces of 6°?
An engineer group studies on the design of a tour balloon for Cappadocia. It is planned that the design details will be determined through the use of a small-scale model for a prototype balloon. The prototype balloon will be departing from a hill with 0,30m height. In the small-scale model, a platform with 0.1 m height will be used to simulate the hill. a) Determine the initial vertical speed (Vo) of the balloon when the initial vertical velocity for the model is found to be sm/s.

Wind provides an increasingly important source of renewable energy in certain locations of the world. In fact, wind was the second largest renewable energy source worldwide (after hydropower!) and provided more than six percent of global electricity in 2020; in the U.S. that number was 8.4%. Suppose that wind turbines can convert up to 30% of the kinetic energy of incoming wind blowing through their blades into electricity (i.e., useful shaft work). In the following, we will analyze the power output of a wind turbine with a diameter of d 80 m placed at an offshore location where the wind blows steadily at an average speed of 20 knots. Explicitly state all relevant approximations or assumptions. = (a) Draw a diagram that includes appropriate elements for assessing the amount of work extracted from the wind turbine. Your diagram should have annotated any known or approximated proper- ties. What is your system and surroundings? What kind of boundary divides these two? Hint: In terms of…
4. The Wright brothers used a very thin wing on their 1903 flyer. In addition, they made extensive use of a homebuilt wind tunnel to test their wing designs. span, b chord, c Model of Wright Flyer (a) The Wright's wind-tunnel models had chord length, c, of about 0.04 m and wing span (length) of 0.26 m. The wind tunnel operated at approximately the same wind speed as the full-scale aircraft - about 13 m/s. Estimate the drag (friction) of a single wind-tunnel model wing under standard conditions (o = 1.225 kg/m³, = 1.7894 x 10-³ kg/s-m). Note that the wing is mounted in the wind tunnel so that both upper and lower surfaces are exposed to the flow. (b) The full-scale 1903 flyer had a chord length of 1.9 m and a wing span of 12.3 m. Estimate the drag (friction) of a single full-scale Wright flyer wing flying at 13 m/s under standard atmospheric conditions. (c) Consider the main wing configuration, which consisted of two wing surfaces (biplane) connected by 18¹ cylindrical rods. We will…

An engineer group studies on the design of a tour balloon for Cappadocia. It is planned that the design details will be determined through the use of a small-scale model for a prototype balloon. The prototype balloon will be departing from a hill with 30 ? height. In the small-scale model, a platform with 0.1 ? height will be used to simulate the hill. a) Determine the initial vertical speed (?0) of the balloon when the initial vertical velocity for the model is found to be 3 ?/?. . b) How long will the prototype reach the height that the model reaches within 33 minutes? . c) Calculate the corresponding height (ℎ) for the prototype when the height is 60 ? for the model.
