دانلود جزوه تاثیرات برخورد آذرخش (رعد و برق )با سازه و بدنه هواپیما

در اثر بالا رفتن هوای گرم از یک طرف و پایین آمدن هوای سرد از طرف دیگر در درون ابرها و تلاطم هوای درون ابر و در نتیجه اصطکاک ذرات هوا و قطرات آب موجود در آنها با یکدیگر ، بارهای الکتریکی بسیار زیادی در آنها ایجاد میشود .با قرار گرفتن ابرهای باردار در کنار یکدیگر یا مجاورت آنها با سطح زمین و در اثر اختلاف پتانسیل الکتریکی بین آنها ، تخلیه ناگهانی بارهای الکتریکی رخ میدهد که منجر به بروز پدیده رعد و برق میگردد .در صورت عبور هواپیما از میان این جریانهای متلاطم علاوه بر احتمال برخورد تگرگ با بدنه ، فشارهای مکانیکی بسیار زیاد در اثر تلاطم هوا به بدنه و سازه هواپیما وارد خواهد آمد

۴,۳۷۰ تومان

Introduction For conventional aircraft, the empennage or tailplane normally takes the form of a single vertical fin and horizontal surface, these are fitted to give the aircraft directional and longitudinal static stability respectively and are mounted at the tail [rear] of the aircraft.

Wings were previously referred to as main planes; they produce the lift that supports the aircraft in flight. When air flows over the top surface of a wing from the leading edge [Le] to the trailing edge [Te] the distance that it has to travel is increased by the camber [curve] of the surface compared with the distance that it would have to travel when passing under the wing, as shown in diagram 3.1 above. The air flowing over the cambered surface increases its velocity, which results in a decrease in the static pressure above the wing. The amount of lift produced is dependent on the speed of the air over the wing, the camber and the surface area of the wing.

دانلود Introduction to Structures & fuselage

Since the advent of powered flight aircraft designers and manufacturers have made use of available technology, striving to build aircraft that are faster and can carry a greater load a greater distance than their previous design and their rivals. Competition to produce the best machine has fuelled research and development; the dramatic leaps in aviation technology were made in the First, Second and Cold Wars of the twentieth century.

The fuselage forms the main body of the aircraft to which the wings, tail plane, canards, vertical fin and in the case of a single engine aircraft the engine is attached. In some aircraft designs the landing gear is also directly attached to the fuselage structure.
