Trent family turbofan engines have been pushing civil aviation boundaries for nearly three decades. Company has become world's leading engine supplier in business aviation for six decades. Engines power largest, fastest and longest-range business jets
ARINC 429 is the most common data bus for commercial aircraft. Uses unidirectional transmission over twisted pairs at 12.5 or 100 Kbps. Developed by ARINC Corporation for aviation communications
Thrust reversal diverts engine thrust to provide deceleration after landing. Most commercial jet engines continue forward thrust even when idle. Systems reduce landing roll by quarter or more. Reverse thrust must be manually selected and shut down after landing
Propeller is a rotating hub with helical blades creating linear thrust through fluid. Principle derived from stern sculling, extending blade arc through 360°. Most marine propellers are screw propellers with helical blades on horizontal shaft
Airships are powered, dirigible aircraft using buoyancy from lighter-than-air gases. Early hydrogen airships were flammable, later replaced by non-flammable helium. Modern airships can lift 3,000 pounds to 4.5 km altitude
Lockheed developed four-engine turboprop military transport aircraft in 1951. First flight occurred in 1954, production began in Marietta, Georgia. Original design featured Allison T56 engines with three-blade propellers
