Airbus and CFM  are testing an open fan engine architecture. This is to accelerate the development of advanced propulsion technologies on an Airbus A380. Ahead of the A380 test flights, CFM will perform engine ground tests.

 Very interesting news from Etihad Airways that signed a draft agreement for 7 Airbus A350F during the Singapore air show.! Etihad used to have 5 A330-200F some of them scrubbed or passed to other airways. The airline has signed a letter of intent for the A350Fs during the Singapore air show. Tony Douglas- Etihad Aviation Group chief    mentioned that they will use  Rolls-Royce Trent XWB engines.

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…. 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…. 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 sırada k
