1、ACRP Problem No. 12-02-15 Alternative Aircraft Ground Propulsion to Reduce Carbon Footprint ACRP Staff Comments: This study appears to be significantly underfunded. Suggest $450,000. TRB Aviation Group Committees Comments: AIRCRAFT/AIRPORT COMPATIBILITY CMTE - Research into alternative means of grou
2、nd propulsion of aircraft should produce valuable results. Much is being researched in this field by aircraft makers and airlines alike. Needs enough data points to validate the model. ENVIRONMENTAL IMPACTS OF AVIATION CMTE - Neutral. Virgin and possibly others airports/airlines have looked into thi
3、s. However, not sure that electric tugs would have the capacity for larger aircraft. The objectives and proposed research need refinement. It appears to be a simple math exercise to compare taxi emissions with ground tug emissions and not worth the time or funding that is being requested. Review Pan
4、el Comments: Not recommended Airlines have already looked into this issue and have determined that barriers to implementation are too extensive. AOC Disposition: No funds allocated. No discussion. A AC CR RP P Problem NumberProblem Number: 12-02-15 I. Problem Title FY2012 Focus Area: Yes Alternative
5、 aircraft ground propulsion to reduce carbon footprint II. Research Problem Statement a. It is not known if there may be benefit by using alternative aircraft propulsion systems to shuttle aircraft to runway. Ground based propulsion is currently used to move aircraft away from gate and to move aircr
6、aft from gate to some maintenance bases. Records are publicly available for taxi-in and taxi-out times for airports within the US. Emissions generation information is also publicly available from the US EPA and the ICAO Engine Database in order to determine emissions generated during taxi operations
7、. Aircraft such as the Boeing 737, Airbus A320, Embraer EMB145, and Bombardier CRJ are used for short haul flights with rapid cycle times. Potential exists to reduce carbon footprint by not using aircraft propulsion engines to move aircraft while on the ground. Aircraft gas turbine engines operate i
8、nefficiently at ground idle and taxi, and there may be a trade-off where it would be more beneficial to use a cleaner form of energy to move the aircraft from the gate to the runway, based on the average taxi-in and taxi-out times for different airports. b. Alignment with FY2012 Research Areas: i. A
