The Titan of Turbofan Technology, the Rolls-Royce Trent 700, is the powering force behind the popular Airbus A330 and famous Airbus Beluga XL. Moreover, the Rolls Royce Trent 700 has earned a stellar reputation by providing the best configuration of efficiency, reliability, and performance.
Apart from this, the Trent 700, originating from the famous distinguished RB211 engine, was the first member of the Trent family. Furthermore, that was Rolls Royce’s most refined engine family, launched in the early 90s to surpass the expectancy of aviation power plants.
The Developmental Milestones of the Trent 700:
Market Demand and Initial Considerations
- Airbus launched the A330 twin-jet aircraft in June 1987, which was a call for more powerful engines in the aviation industry, and this further initiated the research for more refined and powerful engines.
- Besides, at that time, the engine choices were highly limited to General Electric CF6-80C2 and Pratt & Whitney PW4000 engines. Moreover, other alternative options at that time were finite and couldn’t fulfill the power demands.
- Apart from this, to meet the market demand, the Rolls-Royce team researched the development of the RB211-700 variant. Furthermore, this development resulted in the famous Trent 700 series.
Investment and Engine Enhancement
- Moreover, Rolls Royce put over $540 million into the RB211 series upgrade for the Airbus A330.
- Furthermore, with development, the priority shifted to the RB211-524L unit, equipped with a bigger fan and an extra turbine stage.
- The targeted thrust range for the RB211-700 variant was over 65,000 and 70,000 pounds (290 and 310 kilonewtons).
Customer Validation and Orders:
- Hence, Cathay Pacific, In April 1989, ordered ten Airbus A330s, all of which came with RB211-524L engines.
- Furthermore, in June 1989, Trans World Airlines (TWA) ordered Twenty A330s with RB211-524L Rolls Royce Trent series engines.
- The deal with TWA is over 620 million U.S Dollars, moreover showing the faith of Trans World Airlines (TWA) in Rolls-Royce’s technology.
Design Completion and Testing:
- As a result, the development of the Rolls Royce Trent 700 design, with a bigger fan and higher thrust power, was finalized by February 1992.
- Emphasis this, testing the first Rolls Royce Trent 700 engine succeeded in July 1992.
- Consequently, the previous variation, the Rolls Royce Trent 600, production stopped due to the introduction of the Rolls Royce Trent 700 series, as the Trent 600 no longer attracts clients.
Certification and Commercialization:
- Hence, in June 1991, the Rolls Royce Trent 700 series engines Certification Application was submitted and granted in January 1994.
- And finally, the very first Rolls Royce Trent 700-Powered Airbus A330 flew in August of 1994.
- For this reason, Cathay Pacific also started preferring Rolls Royce Trent 700 engines, and from March 1995, they began ordering planes with Trent 700 engines.
Extended Operations Approvals:
- Conversely, in March 1995, the Rolls Royce Trent 700 got a 90-minute ETOPS approval.
- However, for this reason, in December 1995, ETOPS extended its clearance to 120 minutes. By May 1996, it extended to 180 minutes.
- Furthermore, the Rolls Royce Trent 700 proved its Reliability and performance capabilities through long-distance operations.
