La modelele de viteza se castiga, se zice, in jur de 5% la eficienta elicii.
Multa, multa bafta.

...iar cu o singura pala nu mai apare acest fenomen
- adica se echilibreaza singura?
Dar 1 pala nu are mai putina putere de ridicare decat 2?
Poate cineva priceput ne lumineaza :wub:

O elice monopala poate fi echilibrata, doar, static. Se poate face un compromis si regla contragreutatea pentru a avea vibratii minime la o anumita turatie, dar, nu sunt sanse sa avem vibratii mici pe o plaja larga de turatii. La captivele de viteza, unde sunt utilizate deobicei, nu este un impediment, deoarece motorul lucreaza la turatia maxima.

o intrebare: "care este cel mai rapid elicopte din lume?"...o sa va minunati ca e Chinook-ul american, ala cu doua rotoare. Explicatia - tine de marea problema a elicopterelor. Si anume - curgerea supersonica la varful palelor. Asta e cea mai mare limitare a elicopterelor. De aceea rotoarele mari se invart mai incet. Viteza palei la un moment dat se aduna cu cea de inaintare a elicopterului iar viteza rezultanta < 340m/s parca asta e viteza sunetului. de fapt nici nu poate ajunge acolo - unde de soc oblice sau drepte. (vorbim iarasi de aerodimanica transonica sau supersonica)
O elice monopala ar duce la cresterea turatiei (pentru obtinerea aceleiasi portanta - si gata buba - sau se scade drastic viteza maxima de zbor. (la "coase" acolo e alta poveste elicea coasei avand pala de 5 - 6 cm).
Mie mi se pare o "codobatura" - mai degraba mai multe pale decat mai putine...
Primul model - cu cele doua motoare care trag de rotor - in varianta aceea nu ar fi nevoie de elice anticuplu. caci asa se numeste elicea din coada.
Dragos - cauta un tratat despre asimetria laterala a portantei la elicoptere...si la 30 de pale si la doua asimetria asta se manifesta. Doar la punct fix nu exista. Cand ne mai gasim - cu creionul in mana iti explic cum e...si mai ales cum se anuleaza - mecanic - prim miscarile palelor.
