The function of an Air Cycle Machine (ACM) is to control the air in the cabin and <br /> <br /> flight deck of an aircraft to comply the airworthiness requirements with respect to the <br /> <br /> pressure, oxygen content, and temperature. Due to the importance of ACM, a <br /> <br /> laboratory instrument is needed to increase student’s understanding on the working <br /> <br /> process of the system. The Aerospace Engineering Study Program of ITB intends to <br /> <br /> develop an ACM laboratory instrument as a part of the AE3180 Aircraft-Systems <br /> <br /> lecture activity. <br /> <br /> This research aims to develop an ACM laboratory instrument as mentioned earlier. <br /> <br /> The first step is determining the design requirements and objectives of the ACM <br /> <br /> based on a literature study. The second step is to define the ACM configurations and <br /> <br /> to select the primary components. The calculation of the air properties in each station <br /> <br /> of the ACM working process is carried out by using the primary component <br /> <br /> specifications of the configurations. The final step is to estimate the cost of the <br /> <br /> primary components for the selected configurations. <br /> <br /> The research results in two configurations namely the one which uses the Simple Air <br /> <br /> Cycle (SAC) basis and the other uses a regenerative cooling in the Three Wheel <br /> <br /> Bootstrap Air Cycle (TWBAC). The calculation results show that the air properties of <br /> <br /> the two configurations have significant difference of cooling ratio. The Claw <br /> <br /> Compressor C-DLR 150 60Hz is chosen as the ACM power source and the <br /> <br /> turbocharger GT0632SZ for the turbine. The targeted output temperature to be less <br /> <br /> than 10oC has been realized for the selected compressor and for a specific <br /> <br /> environment condition in Bandung.
