"About the rolling disturbance caused by the joint work of a rocket carriers LPR Engines"

Main page




The problem of the rolling disturbance moment is considered arising during the joint work of a lot of liquid propellant rocket engines (LPR Engines). The engines are supposed to be located on the equal distances along the circle as for example on the A- section of the heavy rocket carrier N-1.
The simple mathematical models are proposed for the qualitative explanation of some phenomenon being observed during the flight experiments, namely:

  1. The arising of the disturbing moment around the longitudinal axis of the rocket caused by the jets twist during the joint work of all of the rocket engines.
  2. The absence of such a moment in the case of the gates in the working engines chain (two engines located on the opposite ends of the diameter are turned off).
