Abstract:
(EN) A main engine is operated at an efficient rotational frequency to match fluctuations in propeller inflow velocity, and fuel efficiency is increased. The divergence between a rotational frequency command and measured variations in rotational frequency (NE) of a main axle (13) or the main engine (12) is inputted into a proportional-integral-derivative (PID) computation unit (16), and feedback control is performed on the quantity of fuel supplied from a fuel injection device (15) to the main engine (12). The propeller inflow velocity of a propeller (14) is detected and inputted into a computation unit (17). The rotational frequency command is adjusted such that the control point moves along an efficiency curve in response to fluctuations in propeller inflow velocity.
(FR) L'invention porte sur un moteur principal actionné à une fréquence de rotation efficace pour correspondre aux fluctuations d'une vitesse d'admission de l'hélice, et dont le rendement de carburant est accru. La divergence entre une commande de fréquence de rotation et des variations mesurées dans la fréquence de rotation (NE) d'un axe principal (13) ou du moteur principal (12) est mise en entrée dans une unité de calcul proportionnelle-intégrale-dérivée (PID) (16), et une commande de rétroaction est réalisée sur la quantité de carburant délivré à partir d'un dispositif d'injection de carburant (15) au moteur principal (12). La vitesse d'admission de l'hélice d'une hélice (14) est détectée et mise en entrée d'une unité de calcul (17). La commande de fréquence de rotation est réglée de telle sorte que le point de commande se déplace le long d'une courbe de rendement en réponse à des fluctuations de la vitesse d'admission de l'hélice.
(JA)  プロペラ流入速度の変動に合わせて、効率の高い回転数で主機を運転して燃費の向上を図る。回転数指令と実測された主軸13または主機12の回転数Nの偏差をPID演算部16に入力して燃料噴射装置15から主機12へ供給される燃料の量をフィードバック制御する。プロペラ14へのプロペラ流入速度を検出し演算部17に入力する。プロペラ流入速度の変動に対応して制御ポイントが効率曲線に沿って移動するように回転数指令を修正する。
