Description

Modular power equipment and the aircraft provided with lifting rotor

Technical field

The present invention relates to a kind of modular power equipment, further relates to a kind of aircraft for being provided with lifting rotor, the flight Device is driven by power-equipment to be rotated.

The power-equipment of this aircraft generally includes to drive the turbogenerator of main-gear box.

Turbogenerator generally includes the gas turbine for possessing gas generator, gas generator driving work turbine rotation Turn.Work turbine can be independently of so-called " freedom " turbine of gas generator.The gas generator generally has at least one The individual compression stage that compressed air is supplied for combustion chamber.

Main-gear box includes rotor mast, for driving lifting rotor to rotate.In addition, the main-gear box can include one Delivery outlet is to drive rotor, for example, the rotor of the yawing rotation of aircraft described in drive control.

Attachment means and angle transmission launching apparatus are then it may be possible to be placed between work turbine and main-gear box.Example Such as, this attachment means include being used for the part for adjusting the angular displacement between two rotary shafts.

A kind of turbogenerator is generally horizontally set in support platform.In other words, the output of turbogenerator Axle is horizontal.On the contrary, the main-gear box that support platform is carried is in substantially vertical position, rotor mast by Substantially vertical main-gear box driving rotates.

Older generation's turbogenerator generally there are the sizable problem of weight and volume, and this makes them be difficult to install.More Say, such older generation's turbogenerator is it is possible that of a relatively high fuel consumption body.

But, some modern turbogenerators are relative compacts.The turbogenerator is known to include single compression stage And combustion chamber, it is " inversion type " that combustion chamber, which is stated to be, and the overall dimensions of turbogenerator is dropped significantly small.For convenience For the sake of, and in order to readily recognize it, such turbogenerator is referred to as " close-coupled turbogenerator ".

In order to improve the performance of close-coupled turbogenerator, particularly its fuel consumption, power-equipment may include hot friendship Parallel operation.Although turbogenerator is strictly close-coupled, heat exchanger is found to be bulky on the contrary.For example, pass through Using the hot gas obtained from the delivery outlet of turbogenerator, heat exchanger be used to preheating turbogenerator compression stage it is defeated Air between outlet and the combustion chamber of turbogenerator.

Then, the heat exchanger is secured to heating fresh air on turbogenerator, meanwhile, fresh air is entering Compressed before combustion chamber by gas generator.

Therefore, fresh air is inhaled into turbogenerator, then undergoes each compression stage and compresses.That is compressed is fresh Air is directed into heat exchanger, to be heated before combustion chamber is reached.In this case, compressed air and combustion Expect a combust, so as to produce hot gas, it expands by least one turbine.Turbogenerator can thus include being connected It is connected to the turbine of multiple grades of the compressor and is rotated including free work turbine, these turbines by the hot gas.Then, Hot gas is collected by heat exchanger, so that before hot gas is discharged into air, heating sucks the fresh of turbogenerator Air.

Relatively low fuel consumption is shown as with it by contrast, including the component of close-coupled turbogenerator and heat exchanger Then it is found compared with traditional engine, volume is bulky.

However, component as arrangement is not obvious.

Heat exchanger is in place to the width and/or height and/or length that can cause to increase aircraft skin.Then, The total surface area of aircraft, particularly its front surface area add compared with conventional arrangement.This can cause the air of aircraft Dynamics towing increase.

The close-coupled turbogenerator of arrangement connection heat exchanger can result in significantly changing in aircraft center of gravity position, For example, this may cause adverse effect to the wing of aircraft.Particularly, in order to ensure the static stability of aircraft, vertically Then aircraft is therefore needed to formulate specific dimensions with horizontal stabilizer.

The content of the invention

It is therefore an object of the present invention to propose such power-equipment.

According to the present invention, power-equipment is provided with main-gear box and turbogenerator, and main-gear box has substantially vertical rotation Wing mast, the mast are suitable for the propeller hub of rotary wing, and turbogenerator has output shaft to drive the main-gear box, should Power-equipment has the heat exchanger being fixed on the turbogenerator.

The power-equipment has following conspicuousness：

Main-gear box has at least one rotational deceleration level being arranged in flat cover and stands upright on the top surface of flat cover On stand, rotor mast passes through the stand；

The turbogenerator includes engine housing, and output shaft stretches out in engine housing, when engine housing cloth Put output shaft when on the top surface of flat cover to insert in flat cover, output shaft is basically parallel to rotor mast, and engine housing exists Deviate on longitudinal direction relative to stand and do not contacted with stand；And

Heat exchanger is in the rear Longitudinal extending of turbogenerator, the placed longitudinally position in the opposite direction of rotor mast In the front of turbogenerator.

This power-equipment is not tilting gearing.Because stand is relative to flat cover remains stationary, so, turbogenerator quilt Prevent from moving relative to flat cover, and power-equipment is static relative to support platform.

In other words, the vertical longitudinal direction side of the vehicles relative to power-equipment and/or provided with the power-equipment To turbogenerator is disposed between rotor mast and heat exchanger.The observer that power-equipment is laterally observed in side can To observe this feature.

By being arranged in the symmetrical anterior-posterior plane of power-equipment and the vehicles, heat exchanger can be by accurately fixed Position is in a lengthwise position.

In a modification, by being placed in a clinoplain, heat exchanger can be arranged tiltably, the inclination Plane is extending certain altitude relative to anterior-posterior plane and vertical is being angled up.This angle then can be by observer along height See during the observation power-equipment of degree direction.

What why flat cover was said to be " flat " is because the size in its short transverse is significantly less than longitudinal direction and horizontal Upward size.

For example, the size in its short transverse is about 150 millimeters (mm), and its lateral dimension is about 500mm number Magnitude, so that bull wheel can be put into wherein, its longitudinal size is about 1 meter of the order of magnitude, so that being put into gear System.The height and about 300mm diameter that the size that stand is presented is about 400mm.These numerical value are all in an illustrative manner Provide, especially for the flat feature for illustrating flat cover.

The power-equipment proposes the device with two modules, and they are independent before being secured together, i.e., Main-gear box and turbogenerator, engine are that close-coupled turbogenerator is favourable.Therefore, the two modules are different , and exist in two different shells.

Therefore, turbogenerator and main-gear box are all that independent, self-contained is a set of.For example, turbogenerator and main transformer Fast case is all by competent department's certification independent of one another.

The two modules are mechanically coupled together using the mechanical connection of vertical output axle.

Therefore, the turbogenerator can in the case where not influenceing main-gear box from the vehicles removal, otherwise also So.Operator replaces faulty turbogenerator with can not having difficulty with another turbogenerator.

By the output shaft extended perpendicularly out out of engine housing, turbogenerator is mechanically connected to main-gear box.This Individual characteristic assigns output shaft certain using flexible, and it can allow a certain degree of between turbogenerator and main-gear box Dislocation.

In addition, since the output shaft of turbogenerator is directly inserted into main-gear box, the power-equipment need not then pacify Attachment means or angle driving launching apparatus between turbogenerator and main-gear box.

The power-equipment also allows for avoiding excessively reducing the aerodynamic quality of aircraft.

Can be with the front surface area in aircraft it should be pointed out that installing the turbogenerator associated with heat exchanger Influence.

However, different from conventional configuration, turbogenerator is arranged in substantially vertically by power-equipment suggestion of the invention Position.

In this case, heat exchanger can on the position of basic horizontal Longitudinal extending, lined up with turbogenerator One line and in the size range of conventional covering, therefore, it can take up generally as the space occupied by power-equipment.

When power-equipment arrangement on board the aircraft when, due to turbogenerator aligning, heat exchanger then to flight The influence very little of the anterior face area of device.

Further, since associated with heat exchanger in turbogenerator, turbogenerator can be close-coupled propeller for turboprop Machine, and be therefore small size.Thus, the vertically extending height of turbogenerator is rational.In addition, because output shaft quilt It is directly bonded on main-gear box, the main-gear box can include flat cover, and this is advantageous to the height for optimizing power-equipment.

In addition, the distance of turbogenerator Longitudinal extending is very short, so as to reduce heat exchanger to greatest extent to flight The influence of device balance.The distance that component including turbogenerator and heat exchanger extends in the vertical is by being arranged vertically turbine Engine and minimize.Therefore, unlike those are on aircraft vertical and the influential scheme of horizontal stabilizer tool, this arrangement pair The position of centre of gravity of aircraft has active influence.The lever arm of component including turbogenerator and heat exchanger is relative to rotor Mast is intended to diminish, so that rotation axis of the center of gravity of aircraft closer to rotor.

Therefore, the synergy of these parts of the power-equipment, which allows to obtain one kind and can presented, many expects not To the power-equipment of advantage.

The motive equipment may include one or more following features.

Thus, power-equipment can include the thermal insulation board being arranged between engine housing and the stand.Outside engine Shell and stand are spaced to each other, so that thermal insulation board may be inserted between them.

In this case, for example, thermal insulation board can be provided with the vertical plane between turbogenerator and the stand of main-gear box Plate, and the horizontal panel being especially inserted between turbogenerator and flat cover.

In addition, flat cover may be selected from the front waist section of carrying stand to the rear section Longitudinal extending for carrying turbogenerator. This characteristic especially makes engine housing be separated well with stand.

In addition, flat cover, which can then accommodate the power with bull wheel, reduces level.For example, such bull wheel shows firm, ratio The advantages of epicyclic train is less expensive.

For example, then output shaft can directly engage with bull wheel, or engaged indirectly via overriding clutch or " flywheel ".In whirlpool In the case that turbine surprisingly blocks, such flywheel, which shows, allows lifting rotor to rotate advantage voluntarily to rotate.

The power-equipment can include the groove bindiny mechanism being arranged between output shaft and main-gear box.
