I thought of several titles:<br/><br/>1) Designing mechanisms and blocks of flight vehicles.<br/><br/>2) Design of mechanisms and blocks of flight vehicles.<br/><br/>3) Design of flight vehicle mechanisms and blocks.<br/><br/>4) Flight vehicle mechanism and block design.<br/><br/>Which one is grammatically correct and sounds better (more official)? I'm inclined towards the third one. What do you think?<br/><br/>Best regards,<br/><br/>Alexander
