Evolution

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

Weight and balance

• 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

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

Systems: 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
