Hit Head of Technology with one project to keep peace! (5,3,5)

'keep peace' is the definition.
I know nothing about this answer so I can't judge whether this works.

'hit head of technology with one project to' is the wordplay.
I cannot quite understand how this works, but
'hit' could be 'tan' (tan can mean to beat or hit) and 'tan' is found in the answer.
'of' could be 'o' and 'o' is located in the answer.
'with' could be 'w' (abbreviation) and 'w' is found within the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'to' could be 'shut' (I've seen this before) and 'shut' is located in the remaining letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
