Some observations based on experience with a new generation on Auxiliary Power Unit (APU) installed in a commercial transport aircraft. The subjects considered are operational requirements and efficiency of the APU in the various operating modes. Particular importance is attached to such matters including the factors determining the APU performance characteristics with respect to a cost effective APU system. These considerations are conducted with a look at future development trends seen from the point of view of the aircraft manufacturer. The constructional and control features of the APU are prerequisite to the economical operation of the unit. The present generation of auxiliary power units is exemplified by modular design, direct driven load compressor, load compressor output regulated by inlet guide vanes (IGV), full digital electronic control and single spool/constant speed.
