COURSE OBJECTIVE

To introduce basic concepts of design and trajectory estimation of rocket and missiles.

Unit 01 ROCKET SYSTEMS 10

Ignition system in rockets – types of igniters and igniter design considerations – injection system

and propellant feed systems of liquid rockets and their design considerations – design

considerations of liquid rocket thrust chambers – combustion mechanisms of liquid and solid

propellants.

Unit 02 AERODYAMICS OF ROCKETS AND MISSILES 10

Airframe components of rockets and missiles – forces acting on a missile while passing through

atmosphere – classification of missiles – slender body aerodynamics- method of describing forces

and moments – lift force and lateral moment –lateral aerodynamic damping moment – longitudinal

moment – drag estimation – body upwash and body downwash in missiles – rocket dispersion.

Unit 03 ROCKET MOTION IN FREE SPACE AND GRAVITATIONAL FIELD 10

One dimensional and two-dimensional rocket motions in free space and homogeneous

gravitational fields – description of vertical, inclined and gravity turn trajectories – determination of

range and altitude – simple approximations to burn out velocity and altitude – estimation of

culmination time and altitude.

Unit 04 STAGING AND CONTROL OF ROCKETS AND MISSILES 9

Design philosophy behind multistaging of launch vehicles and ballistic missiles – multistage

vehicle optimization – stage separation techniques in atmosphere and in space – stage

separation dynamics and lateral separation characteristics – various types of thrust vector control

methods including secondary injection thrust vector control – numerical problems on stage

separation and multistaging.

Unit 05 MATERIALS FOR ROCKET AND MISSILE APPLICATIONS 6

Selection criteria of materials for rockets and missiles – materials for various airframe components

and engine parts – materials for thrust control devices – various adverse conditions faced by

aerospace vehicles and the requirement of materials to perform under these conditions.
