Read the following passage and evaluate the statement below.
During testing of next-generation turbofan prototypes, aerospace engineers discovered that deliberately reducing the bypass ratio—the volume of air bypassing the combustion core compared to air flowing through it—unexpectedly diminished overall fuel efficiency at subsonic cruising speeds. While this lower ratio successfully increased the raw thrust velocity of the core's exhaust jet, it simultaneously formed a severe shear layer where this concentrated, high-velocity exhaust violently collided with the slower ambient air. Despite telemetry confirming the core was converting fuel to energy at peak thermal efficiency, sensors aft of the nozzle recorded massive spikes in low-frequency turbulence. To resolve this aerodynamic inefficiency, subsequent iterations featured serrated trailing edges on the nacelle housing.
Statement: Based on the passage, one can validly infer that a significant portion of the energy produced by the engine core was being wasted as kinetic disruption in the surrounding air rather than contributing to forward propulsion.
