The JL-4A/1 that this world of aviation industry benefit develops independently airscrew obtained the model certificate of approval that civil aviation bureau issues at the beginning of September, become domestic fund to obtain the composite material airscrew that model approves, fill domain of airscrew of civil composite material develops blank, major milestone sense is had on airscrew phylogeny.

JL-4A/1 airscrew is form a complete set large put out a fire / come to help on water the composite material airscrew of amphibious plane AG600, this world of aviation industry benefit regards airscrew as the system total division and always bear make an unit, assumed its to develop the mission, on the onshore, water that cooperates lead plane to finish AG600 plane successfully early or late, maritime fly. This model paddle uses paddle of carapace of qualitative paddle of light alloy material, composite material, improved airscrew power performance; Use advanced propeller pneumatic layout is swept past after wing section is mixed, contented airscrew is efficient, low the performance demand of noise; Have change automatically be apart from, be apart from surely, arrange a paddle, prevent be struck by lightning, anti-icing wait for function and paddle exchange ability, have environmental suitability sex of good, on the safe side ensures the characteristic with strong capability high, integratedly.

This world of aviation industry benefit asks strictly according to regulations of civil aviaton comfortable boat, characteristic of industry of manufacturing industry of aviation of our country of base oneself upon, built composite material propeller ability of comfortable boat test and verify and the design that satisfy comfortable boat requirement assure a system. From the clause the requirement sets out, begin a product to be designed independently, make the plan of test and verify such as experiment of material class, component class, product class, finished centrifugal load, fatigue, bird to bump, the accordance test and verify such as test-drive of be struck by lightning, stage wearing experiments. Obtain multinomial innovation positive result early or late, obtain multinomial invention, have the honor to win the 3rd the army and the people aerospace of contest of application of amphibious technology innovation kind only gold prize. Carry project research and development, this world of aviation industry benefit developed the group of airscrew research and development of a high quality. Since development work is started, this world of aviation industry benefit and each unit cooperate actively, finished model qualification satisfactorily authorized job. The success of JL-4A/1 airscrew is developed, it is the significant gain that aviation industry holds to to innovate independently in airscrew industry domain, for our country the development of airscrew of advanced civil aviation laid a foundation, for follow-up AG600 plane development is reached entered the market to offer strong prop up. The development course that reviews this airscrew together ~     June 2011, hand over requisition of airscrew model certificate of approval; In August 2012, determine authorized basis; In December 2014, the ground that finish tries car airscrew consign; In October 2016, the be struck by lightning that finish experiments; In December 2016, finish consign of airscrew of 001 machine form a complete set; In June 2017, the bird that finish strikes a test; In December 2017, finish a key fatigue experiment; In December 2017, cooperate lead plane to finish AG600 plane onshore fly;

In October 2018, cooperate leader flies on water of plane of the AG600 that finish;
China unsaturated polyester resin (UPR)
In November 2018, obtain the 3rd the army and the people gold prize of contest of application of amphibious technology innovation;
China unsaturated polyester resin (UPR)
In July 2020, cooperate lead plane to finish AG600 plane maritime fly;
China unsaturated polyester resin (UPR)
In January 2021, finish 1500 times complete change be apart from circular experiment; In April 2021, finish all exhaustion to experiment; In June 2021, shut total provision; In June 2021, hold eventually model qualification is authorized committee (TCB) the conference; In September 2021, win certificate of approval of civil aviaton model.
