What is the purpose of the nozzles on the respective seat rocket motors?

The purpose of the nozzles on the respective seat rocket motors is to ensure separation between the two seats during ejection. In a dual-seat aircraft like the T-6B, it is critical for the safety of both occupants that the ejection seats separate cleanly and effectively. The design of the nozzles directs the thrust from the rocket motors in a way that allows each seat to be propelled away from the aircraft without interference from the other seat. This separation is vital to prevent potential collisions between the seats, ensuring a safe escape for both pilots during an emergency ejection scenario.

The other options may relate to considerations taken into account during the design of ejection systems but do not accurately reflect the primary function of the nozzles. For instance, while fracturing the canopy could be an initial step in the ejection process, the nozzles specifically facilitate seat separation rather than directly fracturing the canopy. Preventing damage to the SSK (Survival Seat Kit) and minimizing damage to the cockpits may be incidental benefits but are not the primary design goal of the nozzles themselves. Therefore, the design focus remains on achieving a safe and effective separation of seats during ejection, which directly relates to the purpose of the
