Tópico dos aviões

Alguém me pode mostrar as imagens do flight24 da meia noite e 10 (mais ou menos) da madrugada de hoje, dia 5?

Queria ver o tráfego a SW/W de Montemor-o-Novo com deslocação para W ou direcção parecida.

Obrigado.

É que ontem por essa hora vi umas luzes vermelhas pulsantes a uma boa altitude, alternava entre vermelho vivo, vermelho mais fraco e apagava totalmente. Andava devagar e seguiu essa rota... de facto está ali um avião em cima da A13 no mapa que posso ter visto, no entanto o que vi não me pareceu ser avião nenhum.

Podes me dizer que avião era e a rota que fez, sff?

Não tens acesso pelo PC? Pelo menos no PC consegues analisar tudo isso no site para conseguires tirar mais conclusões... Na APP não sei.

CENTRAL FIRE CONTROL SYSTEM (CFC) - B-29 -
By Dale Thompson

The B-29 was equipped with a unique method of operating its machine guns, called the Central Fire Control System. The fact that the plane was pressurized precluded the gunners from having physical access to the guns. So, the General Electric Corporation was contacted to provide a means of remotely operating the guns. GE had experience stabilizing shipboard naval guns in the 1930s, which gave them a head start.

Each of the five turrets on the B-29 is controlled using a sighting station, some of which can control more than one turret. This allows the aiming and the firing of two turrets simultaneously. Each turret and each sighting station has two elevation selsyns, for coarse and fine resolution, and azimuth selsyns, also for coarse and fine resolution. A selsyn is a system comprising a generator and a motor connected by a multiple wire circuit of appreciable length, transmitting currents that turn the motor simultaneously to the same relative position as existing or established for the generator, and repeating instrument indications and valve settings remotely called also synchro.

As the gunner moves the station to track the target, an error signal is developed because the sighting station selsyns and the turret selsyn are not in line. The error signal is first amplified using vacuum tubes in the servo amplifier in an amplidyne, which is a rotary generator-amplifier. The direct current output voltage of the amplidyne is sent to the azimuth and elevation motors in the turret, moving it until it is aligned with the sighting station, causing the error signal to go to zero. Because the sighting stations and turrets are separate from each other, an aiming correction must be applied for the distance between the sighting station and its turret.

This is called a parallax correction, and it is supplied by an electro-mechanical computer that modifies the sighting station selsyn signals before sending them on to the turret selsyn. In addition, to the parallax correction, the computer also adjusts for target speed, target range, aircraft speed, and air density. Aircraft speed and air density are supplied by the Navigator, who sets the aircraft speed, aircraft altitude and outside air temperature on a unit called the Altitude and Airspeed Handset. Target speed and target range are supplied by the sighting station. The sighting station has a display of a circle of dots with a center dot.

The gunner keeps the center dot on the target aircraft and the circle of dots on the targets wing tips. As the gunner tracks the target, the sighting station’s gyroscopes allow the computer to estimate the target’s speed. The circle of dots on the target’s wingspan give the computer a range estimate. With all this information, the computer can adjust the turret’s position so that it leads the target and compensates for bullet ballistics. The gunner fires the guns electrically by depressing a button on the sighting station. Each turret has its own computer, adjusted for parallax with its primary sighting, five in all.

The paths of these various signals converge in one of four control boxes located in the nose, waist and tail of the aircraft. The control boxes allow the switching of sighting stations between their primary turret and their secondary turret. Sighting stations are located in the nose, at each of the two blisters in the waist, at the top of the plane, also in the waist and at the tail.
Turrets area located above and below the cockpit, above and below the aft waist, and in the tail. The forward gunner, who is also the bombardier, has primary control of the upper and the lower forward turrets. The upper gunner has primary control of the upper aft turret. The blister gunners have primary control of the lower aft turret, and must choose which of the two sighting stations control the turret.

If the forward gunner releases control of his gun, the blister gunners get control of the lower forward turret, and the upper gunner gets control of the upper forward turret;. If the tail gunner releases control of his turret, then either of the blister gunners can fire the tail turret. The tail gunner fires only the tail turret. The upper turret gunner is called the OFV+C gunner and is in control of the defense if the airplane, calling out which gunner should fire which turrets. Gunners coordinate among themselves using the intercom system.

Confesso que não percebo puto do site... Não sei consultar :sh)

De qualquer das formas agradeço as imagens que colocaste e chego à conclusão que era mesmo um OVNI.

Canto superior direito, à direita de "Bookmarks". É uma função que de facto passa bastante despercebida.

Atenção que nem tudo aparece no site.

Pode ser que alguém mais entendido te consiga explicar se esse padrão de luz é normal ou não. Sinceramente não sei.

O U-2 continua activo?

(...)

The U-2 was supposed to be replaced by the Global Hawk and the Lockheed Martin RQ-170 Sentinel no later than 2015, until new legislation required any replacement to have lower operating costs. The U-2 costs $2,380 per flight hour compared to $6,710 for the Global Hawk as of early 2014. As a result, the U-2's shelf life was extended to 2023.

Não é bem relacionado com aviões mas pronto...ontem chegando do Porto tive (e todos os passageiros) de passar pelo controlo de passaportes.

Obviamente ouviram-se coros de criticas dizendo se a Madeira acha que é outro país e bla bla bla mas isso nada tem a ver com a ilha (a GNR SEF e afins é tutela do Estado não do GR) mas achei curioso e só deve ser culpa da paranóia pelos atentados recentes em Paris.

Não é teoria nenhuma: o U2 é enviado em poucas horas sobre um alvo específico, ao passo que são precisos dias para recalibrar e reconfigurar rotas de passagem de satélites.

Para além do mais os grupos terroristas sabem a "janela" de passagem de certos satélitos, evitando expor-se.
