DESCRIPTION
Engine
1. The aircraft is fitted with a four Rolls-Royce V-12 supercharged Merlin
Mk 24 engines coupled to Hamilton propellers.
Engine Controls
2.
Throttle Controls
. The throttle is fitted with a gate at +9PSI boost;
the fully forward position gives +14PSI at ground level only. When the
boost control cut-out is pulled, +18PSI is obtainable in either gear.
Mixture Control
3. SU float-type carburettors are fitted. The mixture strength is automatically
controlled by boost pressure, and the pilot has no separate mixture control.
A weak mixture is obtained below +7PSI. The carburettor slow-running
cut-outs are operated by closing the engine master cocks.
