1.1 Background
It takes cutting edge technology and out of the world innovativeness to survive in the aircraft industry. Pratt and Whitney (P&W), a world leader in design, manufacture and service of aircraft engines, is developing technology with the potential to reduce fuel consumption and hence, cut down on the emissions of harmful greenhouse gases CO2. For the average Boeing 777-200ER, this would reduce annual fuel costs by about $1 million and CO2 emissions by about 11,700 metric tons. Besides the above mentioned, P&W’s TALON (Technology for Advanced Low NOx) combustor reduced NOx emissions on the PW4000 by 30% versus the originally certified combustor. In addition, P&W’s next generation of TALONs will make engines like the PW6000 even cleaner and quieter. One can expect P&W to continue their environmental leadership, but they are not alone.
Rolls-Royce (RR), with 50 other partners across Europe, has been conducting research into aircraft noise since 2001 in the largest aircraft noise research project ever supported by the European Commission (EC). SILENCE(R) (Significantly Lower Community Exposure to Aircraft Noise) is performing large-scale validation of over 20 noise technologies that were initiated through EC and national projects in 1998.
While leading aircraft companies like P&W and RR engage in vastly different projects with their respective partners and research centres, their goals are similar:
· Increase efficiency to reduce CO2 emissions and fuel cost savings
· Reduce aircraft noise
· Reduce NOx emissions
It is no mere coincidence that these large companies are working towards the same goals. They are all part of the NASA’s Ultra-Efficient Engine Program (UEET) that is one of the main design drivers powering modern and subsequent future aircraft designs. In the long run, UEET will enable the planet to enjoy cleaner air and the aircraft industry to leave lesser imprint on the environment.
1.2 Objectives and scope
The purpose of this project is to explore the possibilities the UEET program aims to achieve, particularly in the context of commercial aircrafts.
From this project, we will be able to appreciate:
· The UEET program by NASA;
· technical accounts of the evolution of aircraft engines that led to the popular turbofan engine in the present day;
· important economic and regulatory standards and factors that drive the design towards conceptualization of ultra efficient engines;
· technical challenges faced in the conceptualization of UEET program;
· critical view of “the engine of the future”.
