AS 1730/1950-A-3B
Carbon fibre composite construction + duraluminium hub, 3-blade configuration, right rotation, aeroelastic, ground adjustable pitch, blade protection tape.
Ground adjustable B-LINE propellers are designed for applications such as light, ultralight, experimental aeroplanes and also for trikes, motor hang-gliders and gyros with variety of engines with power output limit up to 118 kW(160 HP) (dependent on propeller model) and reduction gears as puller or pusher configuration.
Internal structure of B-LINE propellers enables them to have aeroelastic properties. This technology is the invention of PESZKE company, resulting in optimal engine power receive. B-LINE propellers even though ground adjustable only have very close characteristics to flight adjustable propellers, delivering short take off, high cruising speed and low fuel consumption of the aircraft as well. Additionall advantage of B-LINE aeroelastic propellers is the price which is a few times lower than any flight adjustable propellers.
B-LINE propellers have very low weight thanks to modern technologies used in production process which is resulting in very low inertia momentum,very low noise during running is the next advantage. B-LINE propellers are available in 3-blade configuration only.
B-LINE propellers have no hour limitation when service intervals are obeyed.
Construction & technology
Technological design of B-LINE propellers is based on carbon fibre structure with increased elasticity module and epoxy resin. Materials used in construction have elastic properties which make the propellers damage and bad weather conditions resistant. The paint that covers blades guarantees high contamination resistance and slow exploitation wear. Additionally propeller blades are equipped with transparent protection tape as standard.
The hub is a low weight, high strength two piece construction that enables ground blade adjustments. It is rust protected by anodized layer. Hub production uses best sort of duraluminium 7075 and high precision CNC machining.
Approvals & certificates
B-LINE propellers are approved by polish civil aviation department ULC and in ELPROP configuration have EASA type certificate.
