Dualpropulsion

Dualpropulsion refers to a system or vehicle that utilizes two distinct means of propulsion. This can manifest in various forms depending on the application. For instance, in maritime contexts, a dual-propulsion vessel might combine traditional propellers with a waterjet system, offering advantages in maneuverability or shallow-water operation. Alternatively, it could involve a combination of diesel engines and electric motors, known as diesel-electric propulsion, which is common in larger ships and submarines for improved fuel efficiency and reduced emissions.

In the realm of aviation, dual-propulsion can describe aircraft that employ both jet engines and propellers, such as turbopropeller aircraft with supplementary jet engines for enhanced performance during takeoff or climb. Another interpretation involves hybrid systems where one propulsion method serves as a primary means of power, and the second acts as a supplementary or backup system. The goal of dual-propulsion is often to leverage the strengths of each individual system to achieve a more versatile, efficient, or capable overall performance than a single propulsion method could provide. This can lead to optimized operation across a wider range of conditions or improved responsiveness to varying demands.
