Claims (9)

1. Roterende maskine (10) omfattende et apparat til at afbalancere en rotor (18) deri, hvilken roterende maskine (10) omfatter: en rotor (18) omfattende et nav (22), mindst to rotorvinger (24) koblet til navet, og en rotoraksel (28, 30) koblet til navet for rotation dermed; mindst en vingepitchaktuator (56) koblet til de mindst to rotorvinger for at styre en pitchvinkel af de mindst to rotorvinger; mindst en sensor (48, 50) konfigureret til at måle mindst en af en belastning, en acceleration, og en forskydning, der relaterer til en middelværdi af et eller flere bøjningsmomenter, der virker på rotorakslen (30); og en processor (64) koblet til den mindst ene vingepitchaktuator (56) og koblet til den mindst ene sensor (48,50), hvilken processor (64) er konfigureret til at afbalancere rotoren (18) ved: at modtage (102), fra den mindst ene sensor, mindst en måling af enten en belastning, en acceleration, eller en forskydning, der relaterer til mindst en af middelværdierne af bøjningsmomenterne, der virker på rotorakslen (28,30); at bestemme (104) middelværdien af det ene eller flere bøjningsmomenter, der virker på rotorakslen (28,30) baseret, mindst delvist, på den modtagne mindst ene måling over et forudbestemt tidsrum; og at bestemme (106) en pitchforskudt-vinkelværdi for mindst en rotorvinge (24), der muliggør at reducere middelværdien af det ene eller flere bøjningsmomenter, der virker på rotorakslen (28,30).
2. Roterende maskine (10) ifølge krav 1, hvor processoren (64) er konfigureret til at bestemme en pitchforskudt-vinkelværdi for mindst en rotorvinge (24), der muliggør at ændre det ene eller flere bøjningsmomenter der virker på rotorakslen (28, 30) til omkring nul.
