Concorde Galleys

 

The British Airways Concordes, have a total of seven galleys fitted throughout the aircraft, from these galleys the rich and famous were served with the finest meals and wines in the world. 

These galleys were intended to be removed and upgraded versions fitted to the aircraft during the next planned ‘D’ check, and major overhaul of the aircraft. The London based design agency ‘Factory Design’ and Terence Conran had been working on new designs for the galleys as part of the ‘Project Rocket’ interior upgrades to the British Airways Concorde fleet.

These galleys consist of three main ones, numbers 1, 2 and 7, and four supplementary galleys, numbers 3, 4, 5 and 6. The galleys are fitted at various locations throughout the aircraft.

Fresh water for the galley water heaters and faucets is supplied from the aircraft pressurized water storage tanks, and waste water is drained overboard via heated drain masts on the underside of the aircraft fuselage. You may spot one of these heated drain mast during a visit to one of the Concordes, which are very obvious as you pass under the aircraft; they are marked with the word “HOT” in red. During the service life of Concorde, the galley ‘beverage makers’ were known to be notoriously unreliable.

GALLEY ONE

 

The No.1 galley comprises forward and aft bulkheads, and top and side panels which house a double oven, with controllers, and two meal tray trolleys. An electrical power supply is provided for the oven, and provision is made for the galley electrical load to be shed from the supplying generator if necessary. An air extraction system is also incorporated for the oven. The galley is located immediately forward of the left-hand forward passenger door.  

Galley Construction

 

The galley number one structure consists of a forward bulkhead, which is bolted to the aircraft forward electronics rack, an aft bulkhead, bolted to the steward’s seat structure, the two bulkheads being joined by an outboard side panel, a top assembly and an oven shelf, which are all bolted to the bulkheads. The oven controllers are secured in the top assembly by bolts and anchor nuts, the oven is bolted to the oven shelf and the trolleys are stored below the worktop and restrained by latches. Access to the electrical terminal blocks is through an access panel in the outboard side panel.  

 

Galley Air Extraction

 

The air extraction system is for the oven housing ventilation. The oven housing is connected to the aircrafts air extraction system through a flexible hose and filter. The flexible air extraction hose is secured to the oven housing with a clip and to the aircraft air extraction system by a bolted flange.

 

Galley Electrical Power Supply

 

The electrical power supply for the galley is taken from the No.2 main 200/l15V AC busbar, through circuit breaker H1895 on circuit breaker panel 21-215. There is provision for the galley electrical load to be shed from the supplying generator if necessary; this applies to all seven galleys.

Water & Waste

 

The water system provides fresh water from the aircraft pressurized water storage tanks and supplies cold water to the galley sink and beverage makers. The waste system disposes of water from the sink by draining it overboard via a drain mast on the underside of the aircraft fuselage.

Pressurized water from the aircraft rear galley pipe system is fed, via an isolation valve located at the top right of unit in Miscellaneous Stowage Compartment. A line drain valve is located in the right-hand wall of the meal tray stowage position beneath the boiler.

The waste water from the sink is drained overboard via a drain mast by operating a drain valve lever located on the face of the galley above the waste bin disposal flap. Access to the drain valve is via a hinged flap located under the work-top on the inboard face of the waste bin stowage.
