Claims (5)
1. Vindmøllegenerator med en forvindrotor (1) og en bagvindrotor (2), som er anbragt koaksialt med hinanden, hvor den ene af forvindrotoren (1) og bag-vindrotoren (2) er forbundet med en roterbar ankerrotor (4) af en generator (3), og den anden er forbundet med en roterbar feltrotor (5) af generatoren (3), hvor en retning, hvor et blad (6) af forvindrotoren (1) er drejet, er aksialt modsat en retning, hvor et blad (7) af bagvindrotoren (2) er drejet, hvor en rotationsradius af bagvindrotoren (2) er udformet til at være mindre end en gyroradius af forvindrotoren (1), men længere end halvdelen af samme, hvilken forvindrotor (1) indbefatter bladet (6), som er udformet i et område uden for et mellemområde af en rotationsradius af forvindrotoren (1), så det har et bladelement bestående af en aerofoil, som er cambered i et tværsnit langs med en rotationsretning deraf, så der sikres et forventet rotationsdrejningsmoment, og er radialt drejet, så der sikres en indfaldsvinkel, som er mindre med en forudbestemt stabil grænsevinkel end en indfaldsvinkel, som tilvejebringer et maksimalt opdriftsluftmodstandsforhold uafhængigt af en radial position, og bladet (6) af forvindrotoren (1) er udformet i et område inden for mellemområdet af en rotationsradius af forvindrotoren (1), som skal drejes radialt, så der sikres en indfaldsvinkel, hvorved en luftmodstand, der indvirker på bladelementet, gøres lille, og en total luftmodstandskraft og en opdriftskraft ledes aksialt uafhængigt af en radial position, så der sikres en ikke-belastningsbetingelse, hvor bagvindrotoren (2) indbefatter bladet (7) med et bladelement bestående af en aerofoil, som er cambered i et tværsnit langs med en rotationsretning deraf, så der sikres et forventet rotationsdrejningsmoment, bagvindrotoren (2) er radialt drejet i et område, som svarer til området, der er uden for et mellemområde af en rotationsradius af forvindrotoren (1), så der sikres en indfaldsvinkel, som er mindre med en forudbestemt stabil grænsevinkel end en indfaldsvinkel, som tilvejebringer et maksimalt opdriftsluftmodstandsforhold til en hvirvelstrøm afgivet fra forvindrotoren (1), og bagvindrotoren (2) er radialt drejet i et område, der svarer til området, der er inden for et mellemområde af en rotationsradius af forvindrotoren (1), så der sikres en indfaldsvinkel, som er mindre med en forudbestemt stabil grænse vinkel end en indfaldsvinkel, som tilvejebringer et maksimalt opdriftsluftmod-standsforhold mod aksial strømning med ingen hvirvelkomponenter.
2. Vindmøllegenerator ifølge krav 1, hvor forvindrotoren (1) og bagvindroto-ren (2) er anbragt tæt ved hinanden, hvilken forvindrotor (1) har tre blade (6), og bagvindrotoren (2) har fire til seks blade (7).
3. Vindmøllegenerator ifølge krav 1, hvor bagvindrotoren (2) har en rotationsradius ca. 0,84 gange mindre end en rotationsradius af forvind roto ren (1).
4. Vindmøllegenerator ifølge krav 1, hvor den stabile grænsevinkel ligger i området fra 2 til 5 grader begge inklusive.
5. Vindmøllegenerator ifølge krav 1, hvor mellemområdet i forvindrotoren (1) er mellem 40 til 60 % begge inklusive af en rotationsradius af forvindrotoren (1)·
