Rolls Royce Aero-Engines Test bed 58 is protected by fire alarm & detection, voice alarm, high sensitivity smoke detection, control room fixed fire suppression & test cell engine suppression. The complete M&E fire project has been designed, installed and commissioned by Spectrum Fire Protection (UK) Ltd, Aldridge, United Kingdom.
For Spectrum, the project has ran from an initial design concept in 2006 formulated by Spectrum through to handover of the complete installation during the summer of 2013. The sheer scale of this project owns itself as being the most advanced jet engine test facility in the world.
Rolls Royce Trent series engines are tested at this facility including the new Trent 900 engine for use on the Airbus A380 super jumbo.
Test cell & Aero-engine C02 Fire Protection
Carbon Dioxide (C02) fire extinguishant gas released to the rear intake of the Trent series engines and at the head of the engine enclosure based initially on a local application design were the requirements for this section of the project.
The manufacturer of the suppression components, Kidde, worked very closely with Spectrum in referencing tried and tested design data to formulate a compliant design from similar projects undertaken in the U.S using NFPA rules.
Spectrum was also responsible for the M&E works including the design, supply and installation of a four area C02 gaseous extinguishant controller complete with desk console mounted “push to fire” main and reserve release units.
The C02 system features 52 main, 52 reserve cylinders, rear intake engine woodpecker nozzles and protection to the pit.
Witness full discharge testing of the C02 system into the test cell was a requirement by Rolls Royce’s insurers Marsh and the fire service to prove the capabilities of the design and installation carried out by Spectrum.
C02 Status Indication
Spectrum has designed and installed custom addressable high intensity LED status indication leading to the test cell enclosure. This provides Rolls Royce engineering staff with both safety and status information of the C02 system including – C02 Enabled, C02 Disabled, C02 gas in manifold, C02 gas released.
The addressable C02 status indication controller uses Inim Electronics EN54 multi-protocol Smartloop range of panels. Inim Electronics Enea range of LPCB certified addressable modules directly control the CO2 status LEDS and the monitoring of standby power supply units.
Novec 1230 gaseous extinguishing agent
Critical operations of Rolls Royce’s new test facility are being protected by Kidde Novec 1230 fire extinguishing agent. The M&E design, installation and commissioning including room integrity tests has been undertaken by Spectrum Fire Protection (UK) Ltd.
