@X086@X05.@X0812 @X03 LONG RANGE ROCKET BOMB
@X08Long range rockets can be made by using multi@X05-@X08stage rockets@X05.@X08 Model
rocket engines with an @X05"@X080@X05"@X08 for a time delay are designed for use in multi@X05-
@X08stage rockets@X05.@X08 An engine such as the D12@X05-@X080 is an excellent example of such an
engine@X05.@X08 Immediately after the thrust period is over@X05@X08, the ejection charge
explodes@X05.@X08 If another engine is placed directly against the back of an @X05"@X080@X05"
@X08engine@X05,@X08 the explosion of the ejection charge will send hot gasses and burning
particles into the nozzle of the engine above it@X05,@X08 and ignite the thrust section@X05.
@X08This will push the used @X05"@X080@X05"@X08 engine off of the rocket@X05,@X08 causing an overall loss of
weight@X05.@X08 The main advantage of a multi@X05-@X08stage rocket is that it loses weight as
travels@X05,@X08 and it gains velocity@X05.@X08 A multi@X05-@X08stage rocket must be designed somewhat
differently than a single stage rocket@X05,@X08 since@X05,@X08 in order for a rocket to fly
straight@X05,@X08 its center of gravity must be ahead of its center of drag@X05.@X08 This is
accomplished by adding weight to the front of the rocket@X05,@X08 or by moving the
center of drag back by putting fins on the rocket that are well behind the
rocket@X05.@X08 A diagram of a multi@X05-@X08stage rocket appears below@X05:@X08

@X08C6@X05-@X080 rocket engine
The fuse is put in the bottom engine@X05.
@X08Two@X05,@X08 three@X05,@X08 or even four stages can be added to a rocket bomb to give it
a longer range@X05. @X08 It is important@X05, @X08however@X05,@X08 that for each additional stage@X05,@X08 the
fin area gets larger@X05.
