Launching Planes from Catapults - Airbus's EcoClimb Project
Just came across this great article:
"While many eyes in the commercial airline industry were undoubtedly watching the U.S. Navy's EMALS (Electromagnetic Aircraft Launch System) testing, it is Airbus that has first stepped forward suggesting commercial applications. Earlier this year the manufacturer announced "Smarter Skies," a series of concepts and promotional videos revealing where they want to be by 2050.
One component in their plan is for an EMALS-like system, though they never directly refer to military subcontractor General Atomics' invention; instead the company calls it "Eco-Climb," writing that "Aircraft could be manoeuvred onto a track system and accelerated using either electro-magnetic motors built into the track or an inductive circuit within the aircraft itself." Starting at 0:52 in the promo video below, you can see they're envisioning a much wider platform than what EMALS uses, this one scaled up to accommodate a commercial jetliner"
