Claims (10)
- エンジンのケーシング(3)内に設けられた前記エンジンの吸気口(2)の上流側に配置された前記エンジン用給気プレナム(12)にして、前記エンジンが機能する時に空気流(7)が流れる導管を一体となって形成する第1の側壁(121)と第2の側壁(122)とを備える給気プレナム(12)であって、各々の側壁(121、122)は、給気プレナム(12)内の空気流(7)の流れ方向に対して横方向の凹部を形成する切欠部(8)を備え、前記エンジンが作動している時に前記切欠部(8)内で空気力学的剥離(6)が生じるようにすることを特徴とする、給気プレナム(12)。
- エンジンの吸気口(2)が、前縁(50)を備え、前記給気プレナム(12)によって形成された導管の内側に突出するリップ部(5)を備え、エンジンの吸気口はさらに、リップ部(5)上に位置決めされる保護グリッド(4)を備え、前記リップ部(5)は、保護グリッド(4)を定位置で保持するのに適することを特徴とする、請求項1に記載の給気プレナム(12)。
- 切欠部(8)が、側壁(121、122)の曲率の急変によって形成され、したがって、第1の側壁(121)および第2の側壁(122)はそれぞれ、鋭いリッジ部(80)を備えること、および前記側壁はそれぞれ、前記リッジ部(80)における2本の半接線を含むことを特徴とする、請求項1または請求項2に記載の給気プレナム(12)。
- 一方では第1の側壁(121)のリッジ部(80)と保護グリッド(4)との間の半径方向間隔(L1)と、他方ではリップ部(5)の前縁(50)と第1の側壁(121)に垂直な保護グリッド(4)との間の半径方向間隔(H1)との比率が、0.1〜10であり、一方では第2の側壁(122)のリッジ部(80)と保護グリッド(4)との間の半径方向感覚(L2)と、他方ではリップ部(5)の前縁(50)と第2の側壁(122)に垂直な保護グリッド(4)との間の半径方向間隔(H2)との比率が、0.1〜10であることを特徴とする、請求項3に記載の給気プレナム(12)。
- 一方では切欠部(8)によって画定された環状面(S3)と、他方ではリップ部(5)の前縁(50)によって画定された環状面(S2)との面積比が、一方ではリップ部(5)の前縁(50)によって画定された環状面(S2)と他方ではエンジンの吸気口(2)によって画定された環状面(S1)との面積比の0.1〜10倍であることを特徴とする、請求項3および請求項4に記載の給気プレナム(12)。
- 各々の側壁(121、122)の切欠部(8)が、30度〜180度の切欠き角度(T)を形成し、切欠き角度(T)は、吸気口(2)に最も近い切欠部(8)によって形成される凹部の端部によって形成されることを特徴とする、請求項1〜5のいずれか一項に記載の給気プレナム(12)。
- 各々の切欠部(8)によって形成される凹部が、90度の凹部底角(81)を含み、底角(81)は、吸気口(2)から最も遠い凹部の端部によって形成されることを特徴とする、請求項1〜6のいずれか一項に記載の給気プレナム(12)。
- 各々の側壁(121、122)が、1つの切欠部(8)のみを有することを特徴とする、請求項1〜7のいずれか一項に記載の給気プレナム(12)。
- 請求項1〜8のいずれか一項に記載の給気プレナム(12)を備えたエンジン。
