ROLLS-ROYCE TRENT 900: A MILESTONE IN AERO-ENGINE WORLD

Extracts from this document...

Introduction

ROLLS-ROYCE TRENT 900: A MILESTONE IN AERO-ENGINE WORLD Rolls-Royce Trent is a family of high bypass turbofan engines manufactured by Rolls-Royce. All are developments of the RB211 with thrust ratings of between 53,000 and 95,000 lbf (236 to 423 KN). Versions of the Trent are in service on the Airbus A330, A340, A380 and Boeing 777, and variants are in development for the forthcoming 787 and A350 XWB. The Trent has also been adapted for marine and industrial applications. The Trent 900 program Launched in 2001, the program has proved to be one of the most successful ever undertaken. Every major target set has been met or bettered, on time and to budget. This is a testament to the organizational and engineering skill of the Trent 900 team at Rolls-Royce. The first engine ran to schedule in March 2003, the flying test bed program ran to schedule between May and August 2004, and the engine has received certification from the European Aviation Safety Agency (EASA) to schedule in October 2004. ...read more.

* The latest orders from British Airways and Singapore Airlines and Thai Airways takes the number of Trent powered aircraft to 116 firm and option A380s, providing a very strong position of 58 per cent of the market. * The competitor (Engine Alliance) share is 42 per cent, split evenly between GE and Pratt & Whitney. Leading technical aspects Fan system * Largest fan system in the industry * Proven swept fan design - low in noise and weight but high in performance * Proven light weight titanium fan case Intermediate and high pressure compressor * Bladed discs throughout * Lowest risk and maintenance cost * Next generation aerodynamics * More efficient airflow throughout engine * Better fuel consumption * Less parts and lower weight * Unique 3-shaft design enables compressors to operate at optimum speeds Combustor * Tiled combustor for lowest maintenance costs * Lowest emission rate * Meets all proposed legislation with margin * Assured value Turbines * Low risk * Optimum performance and lowest fuel burn * Best performance retention * Shrouded turbine blades High pressure contra-rotation * Significantly improves the performance and efficiency of the intermediate pressure ...read more.

Conclusion

It is the world's cleanest high-thrust engine, with emissions well below all current and proposed legislations, generating only 40% of the CO2 per passenger kilometer of an average family car. Despite its size and power it is extremely quiet, meaning that the Airbus A380 has only around one third of the noise level of previous 150 seat aircraft. Trent 900 engine uses a 116-inch swept fan, a low NOx combustor and contra-rotating high-pressure systems which minimize emissions, noise and fuel consumption, making the Trent 900 the most environmentally friendly engine powering the Airbus A380.

It's very important to develop this with pace of time because in aviation nothing is stationary or constant. New technology is always welcomed to take the charge. Trent 900 engines is the product of Rolls-Royce Company which has been pioneered the engine technology by various means. Trent 900 is also an exceptional one which has already earned its place in the aviation world. ...read more.
