Warunek oscylacyjności wahań rakiety jako kryterium doboru długości wyrzutni

Stanisław Dubiel, Ryszard Kurnatowski

The paper deals with the problem of determination of the minimum guide length of a rocket missile launcher of variable velocity. As a criterion, the oscillability of the rocket motion with respect to the mass center after leaving the launcher guides has been assumed. Investigating the equations of the rocket motion we have derived the relations from which we can determine: 1) the minimum velocity of the missile, when it leaves the launcher guides, ensuring the oscillability of variation of the angle of attack; 2) the minimum guide length which allows to obtain such a velocity.
