Cabin Layout
Cabin Layout
• Titan can carry– 34 10 ft PMC pallets– 32 LD1 containers
• Compatible with industry standard AMC containers
• Payload density: 11.8 lb/ft3
• Net volume greater than 747-8F• Not disadvantaged at lower
payload densities
Advanced Cargo Handling System
• Fully automated loading sequence
• Load sensors allow the CG position to be monitored and controlled
• System can be monitored from cockpit

Risks
• Low speed interference drag• Engine off condition• Structural issues• Engine maintenance
Engine Maintenance
Structures: Top Level Requirement Analysis
• Minimum structural weight– High stiffness to weight ratio
materials– Maximise structural synergies
• Maintainable, damage tolerant and reliable– Fewer structural components– Damage tolerant materials– Local strength reinforcement– Avoid complex structural
arrangement
Structures: Material Selection
• Economic viability• Consistent with future trends• Identification of potential
locations

TITAN
Structures: Issues
• Pylon– ½ tonne increase in pylon
weight– Titanium construction– ½ tonne margin for detailed
flutter analysis• T-Tail
– Fully composite tail– Structural synergies between
tail and fuselage structures
Structures: Issues
• Acoustic fatigue– Use of chevrons at engine
exhaust – Use of damped CFRP structure
through fibre coatings and surface treatments
• Wheel up landing– Kevlar fairing
• Engine access– Local kevlar reinforcing

Systems: Electrical
Systems: Flight Deck
• Designed for single pilot operations, but able to support a two-man crew for flexibility
• Five 12”x9” switchable AMLCDs• Large format landscape displays
allow presentation of pilot-selectable system parameters on PFD
• Two extra AMLCD displays provide Class 3 EFBs
• Reduction of dedicated panels 'declutters' cockpit

Propulsion: Benefits
• Over the wing engines – reduces FOD ingestion– allows higher BPR engines
• Bleedless engines decrease fuel consumption and emissions.
Propulsion: Noise
• Wing as noise barrier• Rotor sweep optimisation• Chevrons for reduced jet velocity• Acoustic liner• Potential 20 – 30 dB reduction• ICAO Stage 3 limits
Propulsion: Emissions
• Bleedless engine• Compliance with CAEP 6
requirements• Wheel tug• Advanced TAPS combustor
Aerodynamics: Winglets
• Raked wing tips– Increased sweep locally– Increased wing aspect ratio– Improved low speed
performance– Reduction in drag during
transonic flight
Aerodynamics: Aerofoil
• Supercritical aerofoil– SC(2) Series– 10% t/c ratio over most of wing
• Wing jig-twist and t/c variation for elliptical lift distribution
