Why are flying-boom tankers restricted to a single boom?

There are several reasons why it is hard to support multiple booms on a single tanker: 1) Booms need an operator who is located in the fuselage. Video systems provide for remote control on newer ...

Why don't tanker aircraft have ejection seats?

The problem isn't the relief of stress from dumping of loads. If it was, you would have the same failures happening because of the act of landing, where the wing goes from being heavily loaded to ...

Are aerial tankers converted aircraft or their own designs?

The tankers are "based on", not a regular passenger jet "converted to". The same engines and basic body, but the whole internals are different. The Wiki page for the KC-46 outlines ...

What are these small propellers in the A330 MRTT's wings?

Those two locations you circled out are the under-wing refuelling pods, mounted on pylons (where, I suspect, the A340 outboard engines would be). You can find a picture of them on the A330 MRTT ...

Why don’t flying-boom tankers have collapsible/frangible/breakaway refuelling booms?

You answered it yourself: the potential for damage from a frangible boom is far more than one designed to stay together. On a boom system the refueling probe is rigid, but impact velocities tend to be ...

Are aerial tankers converted aircraft or their own designs?

One counter-example : KC-390 (Embraer) doesn't seem based on an existing airframe, but designed concurrently as tanker and/or military transport from the ground up.

Are aerial tankers converted aircraft or their own designs?

I agree with WPNSGuy that most tankers are derivatives of transports, sometimes also bombers. But there are exceptions for sure. The Dash 80 prototype led to the commercial 707 and the military KC-...

How far could a KC-10 tanker fly if it consumed all of its internal fuel tanks?

Not too hard to work out an educated guesstimate. The CF6-50 used in the KC-10 has a thrust specific fuel consumption of .375-ish lbs fuel/lb-thrust/hour. Takeoff thrust is in the range of 53000 lbs. ...

Why don't tanker aircraft have ejection seats?

It is mentioned in other answers, but I want to point it out explicitely: it's the tanker's role, and to a lesser degree its origin. Big tankers, such as the KC-135, let's call them fleet tankers, ...

Why don't tanker aircraft have ejection seats?

Firstly, any bail out above 20,000 feet has a low chance of survival without supplemental oxygen and tankers usually fly above that height. Also, bailing out of a plane going 450 MPH is an extremely ...
