Project on in-flight trolley design

[keung0726]

halo, i am a full-time student in aviation. I am conducting a final year project about iPad charging station. I am going to storage and charge 30-40 iPads in the trolley using aircraft power. In this project, I will modify the inside structure of existing service trolley.

For the part of literature review, I found some regulation (FAR 25.853 )about that, but not all.
Could anyone provide the related regulations for me, especially in the design of electrical part,?

I want to use connect the trolley to the aircraft power in the galley (maybe 28v dc).
However, I am not sure the what is the socket look like and the location of socket.
Could anyone provide these aspect of information to me?

Many thanks,
Noah

So you're offering to take away someone's i-thing, to plug it into an unknown source out of view of the owner, taking away valuable space in the galley and adding quite a lot of weight, with the purpose of charging it? As opposed to, I don't know, maybe plugging it into the USB port provided at your seat?

No, the airline will provide those iPads to passengers.

If memory serves, there is usually a 120V AC outlet in the galley for the cleaner's Hoover. It uses a US style two flat pin socket.

SAE AS8057 may have the information you need:

AS8057: Minimum Design and Performance of Airplane Galley Insert Equipment, Electrical/Pressurized - SAE International

EASA has used AS8057 as the basis for their own regulation, ETSO-C184, with a number of alterations:

The already exist! Qantas used to use them when they supplied ipads on domestic flights.

Hi QFcrew,

I know it but this is my university. I have to figure the behind technique, also to optimise this product.
