Why are they wearing helmets and carrying guns on the plane?
China's transport, tanker & heavy lift aircraft
- Thread starter Totoro
- Start date
PR shots, and the reporter is very stupid
Is she doing something wrong in that image or is there something about her personality?

When some US units took commercial charter flights to Saudi Arabia in 1990, bullets and hand grenades were issued to those soldiers. Flight attendants and crew were frightened from these trigger happy soldiers with full hands of bullets and loaded guns. But the US troops supposed that they will jump out of wide body craft in a "hot landing zone" like UH-1 in Vietnam war. So some flight crew insisted the commanding officer collects the bullets from soldiers. It took hours to collect and count. But some flight crew bet on their soldiers are not crazy and only demanded to offload any bullets from chambers.

That would be so uncomfortable if it were me to keep the kevlar helmet on through out the flight.
We are going off topic. Lets continue this discussion in private. I have sent you a private message.

Gotta make your neck stiff no doubt, but if it's just a short hop in a mobilization exercise (they kinda look like reservists to me, judging the webbing they wear, active unit infantry now wear tactical vests emulating Western designs) then its fine. A normal flight won't make you break sweat unless the air-con is broken.
To be frank, I don't see any reporter in the pictures, just stewardesses trying to appear helpful and patriotic.
As a matter of course, I would require all the guns to be unloaded while aboard the aircraft.
The ammo they can just carry in their duffel bags.
I will comment on the adaptive winglets concept... not the Y-20/..
This is not new. originally 777 had a folding winglets version that caters to UA ( i think) that will fold its wing tips, for fitiing into gates, UA founded its cheaper just to mode the terminals.
but the 777 wing still has structual attachments for folding mechanisms...
ok so what is winglets.
winglets has its maximum aerodynamic efficiency at what angle? well, they are the best for lowering induced drag when they are at full span (or same diahedral as the main wing). max aspect ratio. duhhh..
but the issue is wing root bending moment generate by long aspect ratio wing.
Antonov claims that for cruise the wing lets will fold out to maximize aspect ratio while at "critical" it will fold back. presume to lower loads = save weight,
bad claim... as typcailly the design critical loads is at high G manuevers and gust loads.
unless antonov wants to design a wing that folds in during high g manuevers... it would not lower loads...
howerver if they are any smart. what one can do is to uplift the outboard ailerons at high Gs (via modern FBW flight control) , to unload the outboard wings so to reduce the critical wing root bending moment (lower weight)... this is done on (some) aircraft (cant tell you which ones). and successfully lowered the design critical loads.
