공기엔진에 대한 권교수님의 이해와 표현은

이 연구에 동참하고 싶은 사람들이나 공기엔진의 개발에 투자하고 싶은 사람들이 공기엔진에 대하여 객관적인 판단을 하는데 큰 도움을 줄 것입니다. 이 카페에 올려지는 권교수님의 글들은 공기엔진의 개발에 '경제적인 보탬'을 주고 있습니다.   제가 공기엔진의 원리를 입증하는 방법에 비하여 권교수님께서 공기엔진의 원리를 입증하는 방법은 듣는 사람이 훨씬 이해하기 쉬울 것입니다. 저는 부산대학교 법대 행정학과를 졸업하였으며 '73학번입니다.   4월 중순에 우리회사에 오시면 그동안 우리가 시도해왔는 시작품들도 보실 수 있습니다. 빠르면 그때까지 완전히 작동하는 터빈형 공기엔진이 완성될 수도 있을 것입니다만 첫작품이라 일정을 정확하게 알 수는 없습니다. 회사에 오시면 한턱 쏘겠습니다.(삼진ENG 이대우사장님이 술값은 댄대요.^^)   공기엔진의 타당성을 입증하기 시뮬레이션은 해석이 용이하면서 가장 조건이 나쁜(분자의 운동방향이 불규칙한 조건) 피스톤 타입으로 했습니다만 <TABLE cellSpacing=0 cellPadding=5 width="100%" border=0> <TBODY> <TR class=over_tr xxonmouseover=mouseOver(this) xxonmouseout=mouseOut(this)> <TD class=text_gray noWrap align=middle>169 </TD> <TD width="100%"> <IMG height=14 alt=응용프로그램 src="http://cafeimg.hanmail.net/hanmail/cf_img/i_exe.gif" width=14 align=absMiddle> <A class=link_board_03 href="http://cafe30.daum.net/_c21_/bbs_read?grpid=6ddx&fldid=87T7&contentval=0002jzzzzzzzzzzzzzzzzzzzzzzzzz&datanum=169&subj=%3Cfont+color%3D%22%230000ff%22%3E%C7%C7%BD%BA%C5%E6+%C6%D8%C3%A2-%BE%D0%C3%E0%C0%C7+MD+%C0%FC%BB%EA%B8%F0%BB%E7%3C%2Ffont%3E&id=4to1WaMX_f90&count=6&dcnt=3&fsize=189941&datatype=e&selectyn=N&fileloc=pds7:/13/o/x/6ddx/87T7/000/00/00000169&avatarcate=2&rowid=AAAAz+AA2AAAj7HAAG&nick=%C1%D6%B3%B2%BD%C4&day=20050221081835&rfile=%C7%C7%BD%BA%C5%E6+%C6%D8%C3%A2-%BE%D0%C3%E0%C0%C7+MD+%C0%FC%BB%EA%B8%F0%BB%E7.pdf&page=1&prev_page=0&firstbbsdepth=0002Yzzzzzzzzzzzzzzzzzzzzzzzzz&lastbbsdepth=zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz&edge=">피스톤 팽창-압축의 MD 전산모사</A> </TD></TR></TBODY></TABLE> <TABLE cellSpacing=0 cellPadding=5 width="100%" border=0> <TBODY> <TR class=over_tr xxonmouseover=mouseOver(this) xxonmouseout=mouseOut(this)> <TD class=text_gray noWrap align=middle>153 </TD> <TD width="100%"> <IMG height=14 alt=응용프로그램 src="http://cafeimg.hanmail.net/hanmail/cf_img/i_exe.gif" width=14 align=absMiddle> <A class=link_board_03 href="http://cafe30.daum.net/_c21_/bbs_read?grpid=6ddx&fldid=87T7&contentval=0002Tzzzzzzzzzzzzzzzzzzzzzzzzz&datanum=153&subj=%3Cfont+color%3D%22%230000ff%22%3E%B0%F8%B1%E2%BF%A3%C1%F8%BF%A1+%B4%EB%C7%D1+%BA%D0%C0%DA%B5%BF%B7%C2%C7%D0%C0%FB%C0%CE+%BA%D0%BC%AE%B0%FA+%C6%F2%B0%A1%3C%2Ffont%3E&id=4to1WaMX_f90&count=19&dcnt=5&fsize=76153&datatype=e&selectyn=N&fileloc=pds16:/35/o/x/6ddx/87T7/000/00/00000153&avatarcate=1&rowid=AAAAz+AA1AAAjo0AAh&nick=%C1%D6%B3%B2%BD%C4&day=20050221111112&rfile=E-C+data.pdf&page=2&prev_page=1&firstbbsdepth=0002tzzzzzzzzzzzzzzzzzzzzzzzzz&lastbbsdepth=0002Zzzzzzzzzzzzzzzzzzzzzzzzzz&edge=">공기엔진에 대한 분자동력학적인 분석과 평가</A> </TD></TR></TBODY></TABLE> 실제의 장치는 터빈타입으로 제작이 진행되고 있습니다.   <TABLE cellSpacing=0 cellPadding=15 width="100%" border=0> <TBODY> <TR> <TD class=text vAlign=top width="100%" bgColor=#ffffff> <TABLE cellSpacing=0 cellPadding=0 width="100%" border=0> <TBODY> <TR> <TD vAlign=top><A href="http://pds16.cafe.daum.net/download.php?grpid=6ddx&fldid=3Ck&dataid=226&regdt=20050312222422&disk=6&grpcode=physicslove&dncnt=N&.JPG" target=_blank> <IMG id=upload_image style="BORDER-RIGHT: #929292 1px solid;
