Abstract
Apparatus, methods and computer programs are provided. In one example, an apparatus is a rocket motor, comprising: a casing having a length dimension, a width dimension and a depth dimension, wherein the length dimension is greater than the width dimension and greater than the depth dimension; and propellant, located inside the casing, arranged to generate a force in a direction that is substantially perpendicular to the length dimension of the casing.
Claims27
A rocket motor, comprising:
- a casing comprising a wall defining a plurality of gas exit apertures, wherein the casing has a length dimension, a width dimension and a depth dimension, the length dimension being greater than the width dimension and the length dimension being greater than the depth dimension;
- solid propellant, located inside the casing, arranged to generate a force in a direction that is perpendicular to the length dimension of the casing;
- and
- at least one filter, positioned between the solid propellant and the plurality of gas exit apertures, configured to prevent unburnt solid propellant from being ejected through the plurality of gas exit apertures.
1 more element
A rocket motor, comprising:
- non-gaseous matter arranged for ejection from the rocket motor;
- a first propellant material arranged to eject the non-gaseous matter from the rocket motor to generate a first groundwards force;
- and
- a second propellant material arranged, following ejection of the non-gaseous matter from the rocket motor, to cause ejection of gas from the rocket motor to generate a second groundwards force, wherein the second propellant material is arranged to be ignited by the first propellant material.
1 more element
A rocket motor, comprising:
- a casing comprising a plurality of elongate side walls at least partially defining a single elongate chamber, wherein the casing has a length dimension, a width dimension and a depth dimension, the length dimension being greater than the width dimension, the width dimension being greater than the depth dimension and the length dimension being greater than the depth dimension;
- and
- propellant, located in the single elongate chamber, arranged to generate a force in a direction that is perpendicular to the length dimension of the casing.
A rocket motor, comprising:
- a casing having a length dimension, a width dimension and a depth dimension, wherein the length dimension is greater than the width dimension and the length dimension is greater than the depth dimension;
- and
- solid combustible propellant, located inside the casing, arranged to generate a force in a direction that is perpendicular to the length dimension of the casing.
