Abstract

A propulsion device (29, Figure 12) for manned and unmanned vehicles is provided. The propulsion device comprises an impeller chamber 1 with 360+ degrees rotation capability around impeller 18. Fluid flow channel 22 has a series of turbulence control canards 23 on an inner surface thereof, and a series of fluid directors 12 located within an opening 21 of fluid flow channel 22. The turbulence control canards 23 are aimed downstream and may be of the same or variable shape, size and distance apart to suit a desirable distribution pattern. The fluid flow directors 12 are placed at exhaust opening 21 and may also be of variable shape, size and distance apart to suit a desirable distribution pattern. By rotation of impeller chamber 1 around impeller 18 controls the position of the exhaust opening 21 in space and thus enables steering of the vehicle (30, Figure 12).

Description

Propulsion device

Background art

At present there are many types of propulsion systems. Systems which use propellers, jet engines propulsion, ramjet engines, rocket engines etc. However each of this engines or propulsion systems which include some rotational parts can be very inefficient at high rotation rates due to turbulence, vibration, noise, heat and cavitation loses. Some solutions like the technical solution described in my patent application GB 1707712.4 solves some of these problems but they can also be further improved.

Statement of invention

This invention propose new propulsion system which is improvement of my patent application GB 1707712.4.

Main conceptual improvement is introducing new impeller design as described in my patent application GB 1615739.8 as well as anti-turbulence canards and fluid directors within fluid flow channel.

Propulsion device can be implemented on manned or unmanned vehicles. Propulsion device works by sucking and ejecting fluid by means of propulsion system impeller. Impeller is driven by motor, which can be electro - motor or some other form of motor like internal combustion motor. Rotational movement of motor's axel is being transferred to impeller axel and by that on impeller itself. As impeller rotate fluid in side impeller is being ejected into fluid channel from where is being ejected trough exhaust in which way thrust is generated. Impeller is placed into impeller chamber. Fluid enters propulsion device trough impeller chamber fluid entry opening and impeller fluid entry openings. At impeller chamber can be placed aerodynamic cover. Impeller chamber can rotate 360 + degrees around impeller by means of gear-motor or just motor. Gear motor is placed inside its housing which is immovably connected with drive motor connector. Drive motor connector is immovably attached to intermediary slider supporter. Around drive motor is placed outer sliders cap which is immovably connected with impeller chamber. At the top of outer sliders cap is placed gear plate which is immovably connected with outer sliders cap. As gear motor is activated rotational movement is transferred trough gear motor axel to gear motor gear which turns gear plate. As the gear plate turns, rotate, in the same rotate outer sliders cap and impeller chamber. On this way is controlled position of exhaust opening and by that also aim and direction of ejected fluid by which entire vehicle is being steered.

As fluid leaves impeller and enters fluid channel it's become very turbulent as consequence of sudden turbulent separation. This uncontrolled turbulence significantly reduce fluid flow velocity and by that overall performance of entire propulsion system. In order to counter this i.e. to control turbulence inside fluid flow channel, upstream of exhaust opening, are placed turbulence control canards.

Turbulence control canards are directed in downstream direction and their function is to reduce violent and uncontrolled turbulent separation of fluid from impeller. On this way fluid flow velocity trough fluid flow channel is significantly increased and by that overall performances of each propulsion device and overall propulsion system is also increased.

Detail description

Propulsion device can be implemented on manned or unmanned vehicles 30. Propulsion device 29 works by sucking and ejecting fluid by means of propulsion system impeller 18. Impeller 18 is driven by motor 9, which can be electro - motor or some other form of motor like internal combustion motor. Rotational movement of motor's 9 axel 10 is being transferred to impeller 18 axel 24 and by that on impeller 18 itself. As impeller 18 rotate, fluid in side impeller 18 is being ejected by means of blades 20 and boundary layer effect into fluid channel 22 from where is being ejected trough exhaust 21 in which way thrust is generated. Within exhaust 21 fluid directors 12 are placed. The role of fluid directors 12 is to help direct fluid as its exits fluid channel. Propulsion device can have more than one drive motor 9 and more than one gear motor 6. Impeller 18 is surrounded by impeller chamber 1. Fluid enters propulsion device 29 trough impeller chamber 1 fluid entry opening 17 and impeller fluid entry openings 19. Within fluid entry opening 17 is placed protective grid 16. At impeller chamber 1 can be placed aerodynamic cover 2. Role of aerodynamic cover 2 is to reduce aerodynamic drag. Impeller chamber 1 can rotate 360 + degrees around impeller 18 by means of gear-motor (or just motor) 6. Gear motor 6 is placed inside its housing 7 which is immovably connected with drive motor connector 8. Drive motor connector 8 is immovably attached to intermediary supporter 11. Around drive motor 9 is placed outer slider 41 cap 3 which is immovably connected with impeller chamber 1. At the top of outer slider 41 cap 3 is placed gear plate 4 which is immovably connected with cap 3. When gear motor 6 is activated rotational movement is transferred trough gear motor 6 axel 37 to gear motor 6 gear 5 which turns gear plate 4. As the gear plate 4 turns, rotate, in the same time rotate outer cap 3 and impeller chamber 1. On this way is controlled position of exhaust opening 21 and by that also aim and direction of ejected fluid by which way entire vehicle 30 is being steered. Fluid is ejected in direction of arrow 15. Within impeller chamber 1 are placed sliders (i.e. sliding rings) 25, Tl and 40. At impeller are placed sliders and 39. At intermediary supporter 11 are placed sliders 28 and 38. Motor connector 8 and intermediary supporter are immovable as connector 8 is attached to vehicle 30. Instead of sliders can be used ball bearings or some other friction reducing mechanisms. Impeller chamber 1 consist fluid flow channel 22 in which are placed turbulence control canards 23 and fluid directors 12.

As fluid leaves impeller 18 and enters fluid channel 22 it become very turbulent as consequence of sudden turbulent separation. This uncontrolled turbulence significantly reduce fluid flow velocity and by that overall performance of entire propulsion system. In order to counter this i.e. to control turbulence inside fluid flow channel 22, upstream of exhaust opening 21, are placed turbulence control canards 23.

Turbulence control canards 23 are aimed in downstream direction and their function is to reduce violent and uncontrolled turbulent separation of fluid from impeller 18. On this way fluid flow velocity trough fluid flow channel 22 is significantly increased and by that overall performances of each propulsion device 29 and overall propulsion system is also increased. Angle of inclination between each turbulence control canard 23 and impeller chamber 1 wall can be in range of 0.1 to 90 degrees dependably of size and shape of canards 23 and their number and distribution. Within one propulsion device 29 all turbulence control canards 23 can be same size and shape, with same angle of inclination relative to wall on which they are attached and with same or different distance among neighboring canards. However within one propulsion device 29 all turbulence control canards 23 can also be different in size and shape, with different angle of inclination relative to wall on which they are attached and with same or different distance among neighboring canards.

Shape, size and distribution of fluid directors 12 within propulsion device 29 can be the same or different in shape and size as well as in distribution pattern and mutual distance.

Propulsion device 29 may include prolongations 13 at impeller chamber 1 in purpose of fluid ejection performance increasing and vehicle 30 lending options if use propulsion device 29 for lending purposes.

Vehicle 30 may also include parachute housing 33 with parachute 34 and light source 35 with cooling block 36 as well transparent windows 31, ventilation holes 32, and many other additions like proximity sensors, thermal cameras, night sensors and cameras, optical and digital cameras, transport containers, weapons, fertilizer and chemical dispensers etc.
