The C-17 Globemaster III uses externally blown flaps, where engine exhaust flows over wing flaps to create extra lift for heavy landings on short runways.
This advanced propulsive lift system allows the aircraft to carry massive payloads while approaching at slower speeds, boosting tactical flexibility worldwide.
Unlike conventional airlifters, the redirected jet exhaust striking large flaps creates a powerful and distinctive landing noise heard near military airfields.
NASA research spanning over three decades helped perfect the blown flap concept, paving the way for the C-17's unmatched short-field performance.
The aircraft can land a 160,000-pound payload on just 3,000 feet of runway, making it one of the world's most capable military transports.
To reduce community noise, operators use steeper approaches and optimized flap settings, balancing quieter arrivals with operational performance requirements.
Serving through the 2040s, the C-17 remains a vital global airlifter, combining extraordinary capability with an unmistakable sound during every landing.
