The invention of the Constant-Speed Drive (CSD) transformed the B-52 Stratofortress, a cornerstone of the US Air Force fleet. The CSD, developed by General Electric in the 1950s, revolutionized the way the turboprop engines on the B-52 operated. Prior to the introduction of the CSD, the engines had a limited range of operating speeds, leading to inefficiencies and maintenance challenges. With the CSD, the engines could operate at a constant speed, regardless of the aircraft’s altitude or speed. This innovation greatly improved fuel efficiency, reduced maintenance needs, and enhanced the overall performance of the B-52. The CSD played a crucial role in ensuring the B-52’s ability to carry heavy payloads over long distances, making it a key component of the US Air Force’s strategic bomber fleet. This genius invention forever changed the capabilities and effectiveness of the B-52, solidifying its place in military history.
