PERFORMANCE ANALYSIS OF STIRLING ENGINE TYPE ALPHA USING THERMODYNAMIC APPROACH BASED ON SCHMIDT THEORY Raden Hengki Rahmanto, Yopi Handoyo, Fahrizal Zain Asrori Corresponding Author: Raden Hengki Rahmanto

Question from Dr. FA. Rusdi Sambada 2022.12.21 13:29:14 Thank you for sharing your research results. As far as I know, making a Stirling motor, especially the alpha type, is very difficult because, on the one hand, it has to be tight, but on the other hand, the friction has to be as small as possible. Is the 228 cc capacity the total capacity or just one of the cylinders? Can the Stirling motor that is made rotate by itself at the start, or does it need assistance at the start so that the Stirling motor can rotate? In your opinion, what field will the Stirling motor be most suitable for in the future? Thank you

Reply from Mr. Raden Hengki Rahmanto 2022.12.21 14:08:20 Thank you for your questions, Yes it is quite difficult to create the engine it self but we manage to do that just barely because it does as you^re saying tight but not too tight. The capacity is from the compression and expansion chamber combined, to rotate the it does need a conditions that is Temperature in compression chamber is at 31.9 Celsius degrees and Temperature in expansion chamber is at 482.2 Celsius degrees but does not need assistance to rotate. In my opinion Stirling engine can be implemented with the help of heat source from the sun or excess heat from manufacture so it can be as clean engine as possible, and also we can assign with generator to create electricity. Thank you Dr. FA. Rusdi Sambada.
