Approximate design scheme OF A ROCKET STARTING FROM THE PIT. ROCKET connected to compartment BY elastic connection and damper

Consider the effect of underwater explosions on missiles that are in mine compartments by apparatus. Class launch vehicle in this case does not affect the merits study.

Differential equations of launch vehicle case motion be written as

  (1)

where .

This equation is solved using the Laplace transform relative to variable  for the following initial conditions:

Then, we have

     (2)

Taking into account that

we have:

(3)

Thus, the operator form of equation (1) is

.  (4)

Simple transformations give:

        (5)

The denominator of the first product in brackets is written differently:

.   (6)

There are two cases [1].

1)                     

Let:

Then, expression (5) takes the form:

       (7)

Given the known relationships

particular solution of equation (1) can be written as follows –

   (8)

2)               

Let:

Then, expression (5) becomes a

      (9)

Using the known value of inverse Laplace transform

particular solution of equation (5) for the given mode of character connection between compartment and launch vehicle housing of underwater vehicle is written as:
