There is a lot of history and science behind airplanes and how they fly. First, you need to know that the Wright brothers invented the airplane, therefore without them transportation wouldn’t be like it is today. Airplanes are made up of many different parts that make it fly such as jet engines which is probably the first thing you would hear/notice about an airplane, or propeller engines which are more traditional. However, engines are not the most important part for a plane to fly. There are actually

ABSTRACT Helicopter is known for being extremely challenging to fly. The helicopter flight controls enables the pilot to attain a controlled flight. The flight controls differ drastically when compared to the fixed wing aircraft. The advancement in flight controls namely fly-by-wire system has resulted in reducing the complexity of the system. The state of the art fly-by-wire system has resulted in increasing the performance and at the same time reduces the workload of a pilot. The four main controls

Introduction Most of the people in the world watch the football match at least once per 4 years for world cup. People are enthusiastic about fantastic spinning goal and non-spin goal which is hard to kick. However, people do not think of how the soccer ball is spinning and not spinning. Also, the people who are playing soccer, do not think much about the principle of the soccer ball applied scientific facts and they are not aware of it. This background is the reason why I want to research, there

It’s a bird! It’s a plane! It’s Superman! In 1938, Action Comics #1, released the first Superman comic to the public. Superman, also known as Kal El, has shown many different powers since his first debut in 1938. This paper will discuss various topics about four of his major powers and explain why they are all impossible for anyone to achieve in real life. Superman’s four major powers that will be discussed in this paper are X-ray vision, being able to fly, super strength, and invulnerability.

gear to the ground; or (2) Any lesser height, not less than eight inches, resulting in a drop contact velocity equal to the greatest probable sinking speed likely to occur at ground contact in normal power­off landings. (b) If considered, the rotor lift specified in §27.473(a) must be introduced into the drop test by appropriate energy absorbing devices or by the use of an effective mass. (c) Each landing gear unit must be tested in the attitude simulating the landing condition that is most critical

paper airplane, one can usually ignore some of these factors, it is still vital to understand them when constructing any successful aircraft. All the forces working to act on an object in flight come in pairs of resistive and assistive forces; gravity-lift and drag-thrust (the former resisting flight and the latter assisting (Spathopoulos). The four forces of flight all affect paper airplane flight, except for thrust, which is negligible because paper airplanes do not have engines or anything capable

calculated. The wing model is severely affected by the loads on along wing direction, across wing direction, vertical direction.NACA 2412 airfoil was taken for designing wing. FLUENT was used for computational fluid dynamic analysis to determine the lift and drag for wing during zero degreed flaps and angled

and the beginning of the 20th (Lilienthal, 1889; Lippisch, 1960) [2, 3], but most of them failed due to insufficient academic knowledge. The result of one attempt was Knoller [5] and Betz [6] demonstrated the flapping wings generate both thrust and lift of the aerodynamic force, also found motion correlations between wingspan, flapping frequency, weight. According to Prandtl’s formulation, Birnbaum [7] developed the first analytical methods for calculating thrust and efficiencies of flat plates in

Minimum weight design of a wing box subjected to bending Abstract: Aircraft wing is one of the best examples of an efficient structural design. A variety of structural arrangements are possible to satisfy design goals. The endeavour is always to arrive at a minimum weight of a wing structure for a given set of design conditions. The main load carrying structure of a wing is the torsion box formed by front spar, rear spar, and top spar & bottom skins. In the preliminary design stages an

To acquire some perspective and information on the current flapping wing MAVs, it is useful to investigate the existing product that has been completed by a variety of research groups, companies and personal maker. Depending on distinct different size, flapping wing air vehicles (ornithopers) can be differentiated into two groups, MAVs and full-size ornithopters. The first group, as mentioned is the vehicles with dimensions less than 0.2m. The second group is relevant to large vehicles. The concerns
