On this all-aluminium engine 5, be also provided with and start interface end 1, for the startup of all-aluminium engine 5 provides external impetus, thereby cancel the electrifying startup pattern that motor car engine adopts, then adopt Split type electric to start, or artificial rocking arm starts.

The retrofit process that the repacking aviation piston engine that the utility model provides is implemented mainly comprises: the repacking steps such as motor type selecting, aircraft propulsion demand analysis and propeller cavitation coupling and motor loss of weight coupling.

The first step, motor type selecting

Leading indicator according to user's request: power, weight, rotating speed, oil consumption rate, volume and price etc., in existing domestic and international motor car engine, select, mainly consider full aluminium, automatically controlled, be with turbo charged high power to weight ratio petrol engine.Power to weight ratio is greater than 1, and oil consumption is as far as possible low.And then finally select according to principal elements such as engine speed, moment of torsion and modification difficulty.

Aviation piston engine as shown in the table, first five items motor is existing external main flow, its power to weight ratio is substantially all in 1 left and right, and power is in 100kw left and right.Therefore, the domestic and imported motor car engine of at present domestic extensive existence is as shown latter 11, and power to weight ratio is all more than 1, and substantially all large than the power to weight ratio of above aeroengine, can reach aviation piston engine weight and power requirements completely.

Second step, aircraft propulsion demand analysis and propeller cavitation coupling

Determining after motor, according to the designing requirement of aircraft propulsion, carry out propeller cavitation and engine performance coupling, be mainly the moment of torsion of considering motor, rotating speed, oil consumption, reliability etc., select suitable propeller cavitation parameter, to reach best effect.And then carry out the excuse Electromechanical Design of motor and propeller cavitation according to aircraft propelling system design and propeller cavitation concrete condition, realize the reliable installation of motor and propeller cavitation and efficiently move.

The 3rd step, the repacking of motor loss of weight and coupling

With regard to modal automatically controlled cylinder sprays turbosupercharging all-aluminium engine outward, the GW4G15T motor of for example Great Wall Automobile company.Can reequip and mate by following several, improve the aviation seaworthiness of motor to reduce quality.

1, can cancel machine electrifying startup, adopt Split type electric to start, or artificial rocking arm starts.Cancel flywheel, dress propeller disc, cancels clutch housing simultaneously.Can reduce about 4+15-10+5=14kg.

2, because oil sump does not need supporting engines, therefore can make the thin plate of the ultralight easy heat radiations such as aluminum alloy into, water tank and oil sump are inherited simultaneously, one shell is dual-purpose, reduce water tank and oil radiator simultaneously, by air-cooled raising radiator effect, reduced cooling liquid quality, also can consider the cooling liquids such as alcohol, necessary time, use in order to do fuel by air-distributor vacuum pipe; Improve machine oil cooling effect, and considered and can suitably reduce oil level 30% tens hours working times one time of engine maintaining.Can reduce 3+2+1=6kg.

3, air condition compressor, oil hydraulic pump, inflating pump etc. are all cancelled, and can cancel its fitting seat hole, belt pulley etc.Can reduce 1+1+1=3kg.

4, can improve generator, adopt high-speed and high-efficiency generator, be contained in spiral by Pan Chu, cancel belt pulley etc., also can, by adopting up-to-date efficient startup generating integrate motor, both solve generating problem, reasonably solve again starter motor problem.Can suitably alleviate 4kg.

5, do not need air-strainer in the air, admission line and intake manifold can adopt composite material, reduce quality; Can alleviate 2+2=4kg.

6, fuel tank and oil pipe etc. can adopt the super light materials such as aluminum alloy, also can consider fuel tank and cooling water radiator to do one, allow oily cooling water, allow water to oil thermal insulating.Reduce duct length simultaneously, can mitigation system quality; Also can consider oil to be stored in wing and to wait other places, to facilitate center of gravity of airplane adjustment simultaneously.

7, the decoration cover piece such as engine bonnet completely can be cancelled, and can alleviate 3kg.

8, by existing storage battery, change the high power density batteries such as lithium cell into, consumer is relatively little, substantially can accomplish that 1kg, with interior, can consider to cancel storage battery, directly adopts super capacitor and generator combination.

By above-mentioned loss of weight step, can alleviate altogether motor dry weight 14+6+3+4+4+3=34kg.By Great Wall GW4G15T motor, 110kg, 110kw calculates, and motor can be accomplished 76kg, fills it up with the unladen mass such as cooling liquid and machine oil and can be controlled at completely in 100kg.

Take China's pterosaur unmanned plane heavyweight as example, general 1000kg gross mass.GW4G15T motor and ROTAX914 aviation piston engine after coupling repacking respectively.

GW4G15T motor (power 110kw) after coupling repacking: fill 200L gasoline (160kg)+100kg=260kg, by 1 hour 8 oil, can continue a journey 25 hours; Batch production unit price 10,000, oil consumption 1600+50=1650 unit at every turn.Use 5 years, 500 times, add maintenance service, annual 2000, spend altogether 15,000,+16,50*,500,+10,000,=85 ten thousand.The life-span of motor car engine, the time, 500*25=12500 hour, can reach substantially probably more than 10,000 hours generally more than 500,000 kilometers.

ROTAX914 aviation piston engine (power 84kw) is installed: fill 227L gasoline, 78kg+182kg(227L)=260kg, by 1 hour 15 oil, can continue a journey 15.1 hours.Unit price 400,000, each oil consumption 227*8, uses 5 years (amounting to 7500 hours, every 1000 hours life-span, at least 7 motors of needs), and 500 times, maintenance service is annual 150000, spends altogether 445.8 ten thousand.

Amount to cost, adopt the life cycle cost of refiting engine be adopt external aviation piston engine 20% less than; Get rid of fuel consume, only consider purchase cost and maintenance, refiting engine expense be external aviation piston engine 1% less than (2.5 ten thousand/3,550,000=0.007).Therefore, the aviation piston engine of reequiping by this patent has very large advantage from cost, and motor band automatical control system itself, engine maintenance is detected with on-line monitoring in the future and has extraordinary expansion to be worth, and existing aviation piston engine is substantially all take Carburetor as main, cannot realize the function such as self diagnosis and electronic monitoring.

Above embodiment is only a kind of mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Its concrete structure and size can be adjusted according to actual needs accordingly.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
