How much faster will boomless flights be?
When in Boomless Cruise, speeds are 40-50% faster than conventional airliners. This means a flight from New York to Los Angeles can be up to 90 minutes shorter. Hybrid routes with overland and overwater segments, such as Chicago to Frankfurt, will also see incremental time savings.
Overture’s advanced autopilot will continuously optimize speed for Boomless Cruise based on real-time atmospheric conditions. Boomless Cruise is possible at speeds up to Mach 1.3, with typical speed between Mach 1.1 and 1.2.
Does this mean Overture is a low boom aircraft?
No, boomless and low boom are distinct concepts. In Boomless Cruise, Overture’s sonic boom does not reach the ground. However, at its full Mach 1.7 speed over water, Overture will generate a sonic boom.
How does Boomless Cruise affect fuel efficiency?
Overture is designed to be most efficient at high subsonic speeds of Mach 0.94 and supersonic speed of Mach 1.7. As aerodynamic drag increases closer to speed of sound, there is a modest increase in fuel burn at low supersonic speeds. Even with this drag penalty, Overture still has plenty of range to fly the longest transcontinental routes, such as Vancouver-Miami.
quindi per non generare boom viaggia a 1.15 mach dove però l'efficienca non è delle migliori. Le performance sono inoltre minate dalle condizioni meteo. Servirebbero dati piu' concreti sulle velocità e i consumi in gioco per valutarne la bontà. Diciamo che se la crocierà sarà a 1.15 mach, quando l'intera aviazione si attesta a 0.85 è un buon risultato ma nulla che faccia gridare al miracolo. Il concorde viaggiava a 2.04 mach in crociera...
