WHERE SHOULD THE THRUST BLOCK BE PLACED?

 THRUST BLOCK IS ONE OF THE MOST IMPORTANT COMPONENT IN PROPULSION SYSTEM THAT IS RESPONSIBLE FOR TRANSFERRING THE THRUST PRODUCED BY THE PROPELLER TO THE SHIP'S HULL.

THUS IT SHOULD BE PLACED IN A STRATEGICAL POINT TO TRANSMIT THE MAXIMUM THRUST .

PONTS TO BE CONSIDERED WHILE PLACING A THRUST BLOCK

1. MAXIMUM THRUST TRANSMISSION
2. LESS PRONE TO VIBRATION
3. LEAST DAMAGE TO MACHINERY COMPONENT DUE TO THRUST

KEEPING THE FOLLOWING POINTS ON MIND , THE BEST POSITION WOULD BE AT THE AFT OF THE MAIN ENGINE  THUS COMPONENTS OF MAIN ENGINE ARE NOT EXPOSED TO THRUST.

NODE POINT OF THE SHIP IS SELECTED THUS THE VIBRATION ON THE SHIP STUCTURE WONT AFFECT THE THRUST TRANSMISSION PROCESS

PLAN VIEW OF SHIP'S AFT STRUCTURE

BY LOOKING AT THE ABOVE PLAN VIEW, IT IS CLEAR THAT THE AREA FOR THRUST TRANSMISSION IS GREATER NEAR TO THE MAIN ENGINE. THUS SUCH AREA IS SELECTED .

TO SUMMARISE, WE CAN SAY THAT THE THRUST BLOCK IS LOCATED AT A POSITION NEAR TO THE AFT OF MAIN ENGINE WITH ADEQUATE STIFFENING IN THE DOUBLE BOTTOM IN THE POSITION OF THRUST BLOCK AND ON THE NODAL POINT.
