Stealth tenology

The very low detectability known informally as stealth tenologies ( stealth from the english ) or also invisibility ,cover various concealment teniques, most used in anes and boats,to make them less visible to radar, how does stealth aircraft technology works. This tenology became notorious in wars su as the Gulf in 1991,although given the recent advances in algorithms of filters Bayesianos,used to process the data received by the radars, as well as improvements in the radars and sensors themselves, has lost effectiveness. However, both United States and Russia and other countries continue to develop and resear stealth tenologies. The current trend is to integrate stealth tenologies on top of more conventional equipment.

Invisibility tenologies are not new. Special operations infantry commandos have always used it, including aircraft using their maneuverability, following the contour of the terrain or using electronic countermeasures. But stealth tenologies are more concerned with the design and composition of the vehicle to drastically reduce the radar eo they reflect.

A mission carried out by a vehicle using stealth tenologies will be revealed to them (for exame) when the target is destroyed. Attacking using surprise, attacking at high speed, and maximizing the use of stealth tenologies maximizes the effectiveness of the attack, making the enemy less likely to defend against that and future attacks. On the contrary, the design concessions involved in making a weapon cometely stealthy means that, if detected, it has little ance of escape.

Stealth tenologies are a combination of several teniques, especially:

Stealth aircraft su as the F-117 are generally used against highly fortified and defended ground targets as centers of command and control or batteries of missiles anti-aircraft. The radars cover the entire airspace surrounding these areas, even overlapping, making it impossible for non-stealth aircraft to enter that area. Stealth anes can be detected, but only if they pass very close to the radars, so even for these anes there are risks. However, a stealth aircraft flying at a suitable altitude and according to a prepared flight an can safely attack radar stations. Once these stations have been destroyed, conventional aircraft can begin operating over the area.

Currently, however, the concept of "strict stealth" that led to the construction of the F-117 and the B-2 is considered obsolete due to advances in remote sensing systems and digital signal analysis.< /p>

The first hunting with a high level of stealth is the F-22 Raptor whose ugin is F-35 JSF. Assuming an adequate combat load, there is nothing to prevent these two aircraft from carrying out combat actions similar to the F-117 (ground attack). However, aerial combat imies certain differences. A stealth aircraft can approa an airborne target with a greater ance of being undetected, allowing it to get a better position for its guided weapons. Certain types of weapons are likely to be avoided by this type of aircraft. With high tenology (common in modern fighters) comemented by active electronic scanners ( AESA ) stealth aircraft can act as control centers AWACS for other anes. Stealth anes are also a good escort for ground attack anes.

Расчет высокопрочных болтов на растяжение

Особенности расчета на прочность элементов, ослабленных отверстиями под высокопрочные болты:
При статической нагрузке, если ослабление менее 15 °/о, расчет ведется по площади брутто А, а если ослабление больше 15 %—по условной площади Лусл = 1,18 Ап.

Монтажные стыки

Монтажные стыки делают при невозможности транспортирования элементов в целом виде.
Монтажные стыки для удобства сборки устраивают универсальными: все прокатные элементы балки соединяют в одном сечении.

Проверка прочности

Проверка прочности сечения на опоре балки по касательным напряжениям:
Балочной клеткой называется система перекрестных балок, предназначенная для опирания настила при устройстве перекрытия над какой-либо площадью.
