Turkish Airlines to buy A350 XWB? THY A350 mi Alıyor?

Resim
Turkish Airlines to buy A350 XWB? Turkish Airlines, Turkey’s flagship airline, is in the negotiations with Airbus to require brand new Airbus A350s! Turkey's biggest airline has more than 160 Airbus aircraft currently in its fleet, 54 of then wide-body aircraft. The airline has been renewing its fleet by eliminating Airbus A340s and ordering new Airbus A330s and Boeing B773s. In addition to 54 Airbus wide body aircraft, the company also has 32 Boeing 773s. The new assigned board members has a great pressure to acquire more wide body aircraft such as Boeing 747s and Airbus A380s. However, even tough the top management expressed interest on these models, Turkish flag carrier airline has not come up with any order on these model but  shown a great interest on B773s and A330s as the airline finds them more efficient. Now Turkish Airlines is to have a great step to acquire a brand new Airbus A350s! This is very surprising interest for anyone and has not...

Live Train 24/7 Train Driver's View Cab Ride Excellent Winter Railway Beautiful Front Window View

Live Train 24/7 Train Driver's View Cab Ride Excellent Winter Railway Beautiful Front Window View  I have recently found a new fun to watch the stream trains a live while the trains are passing the Norwegian beautiful and snowy mountains. It is not as good as watching plane landings and takeoffs but if you need some time for relaxation, it is highly recommended.  This is one of my favorites. If you are interested please leave a comment and I can share some more links, for instance Japanese bullet trains and railways that the trains are operating and at the same time railway workers are working on the lines!

Winglets. Why airplanes need wingtips? Are they useful? Any disagvantages?

Resim
Winglets…. We often see small curves at the wings of the planes and especially of the planes designed in recent years. These curves can sometimes be different from the wing color and can be clearly understood to be added to the wing of the plane later on. We see different winglets in different models of airplane brands, even on the same brand. Are these fins necessary, if so what are the benefits? Are they being used for efficiency? Or are they being used to improve flight performance or drag performance on departure and / or cruising? What was the inspiration for the engineers when the fins were designed? Let's try to find answers to these questions together ... Photo Credit: Airbus Why winglets are needed? The ability of aircraft to fly is due to the different pressures (lift force) applied under and over the wing of the aircraft. Due to the pressure difference between the lower and upper layers of the flap, the air that flows on the flap leaves the fla...

Uçak Kanatçıkları... Neden gerekli oldukları, avantajları ve tasarım süreci.

Resim
  Uçak kanatçıkları…. Uçakların ve özellikle son yıllarda dizayn edilen uçakların kanatlarının ucunda küçük kıvrımlar görüyoruz. Bu kıvrımlar bazen kanat renginden farklı olabiliyor ve daha sonradan uçağın kanadına eklendiği netlikle anlaşılabiliyor. Uçak markalarının, hatta aynı markanın farklı modellerinde farklı kanatçıkları (winglets) görüyoruz. Peki bu kanatçıklar neden gerekli, ne gibi faydaları var, verimlilik için mi kullanılıyor yoksa kalkışta ve/veya seyirde uçak performansı yada uçuş güvenliğini artırması için mi kullanılıyor? Kanatçıklar tasarlanırken mühendislerin esin kaynağı neydi? Bu sorularının yanıtlarını gelin birlikte aramaya çalışalım… Winglet’ler neden gerekli? Bildiğimiz gibi uçakların uçabilmesi, uçağın kanadının altına ve üstüne uygulanan farklı basınçlar (kaldırma kuvveti) sayesinde   gerçekleşir. Kanadın alt ve üst katmanları arasındaki basınç farkından dolayı kanat üzerinde akıp giden hava kanat ucundan uçağı terk eder ve bu...
