Description

Technical Field

[0001] The invention belongs to the technical field of low-altitude aircraft, and in particular relates to a panoramic flight platform. Background Art

[0002] China has made significant achievements in the green industry. In terms of transportation, the new energy vehicle industry has developed rapidly. At the same time, with the upgrading and transformation of electrification, the aviation industry has also ushered in new opportunities. Battery and motor technology are constantly making breakthroughs, and electric vertical take-off and landing aircraft are gradually gaining military and civilian value and broad market prospects.

[0003] Electric aircraft, which have significant advantages such as low carbon pollution, low noise, low cost, small space occupation and strong maneuverability, will bring great convenience to human life and work, and truly benefit mankind. Since the power device of electric aircraft is different from that of traditional fuel aircraft, and it can even be said that it has undergone great changes, the overall layout of traditional fuel aircraft is very likely not suitable for electric aircraft. However, most electric aircraft currently still use the traditional layout or its improved version, without considering the characteristics of electric propulsion. In addition, the weight of traditional fuel aircraft will decrease with the flight time, while the weight change of electric aircraft is minimal, which also puts forward new requirements for the overall layout of electric aircraft. In addition, the traditional independent design method of propulsion system limits the comprehensive optimization design of aircraft. Carrying out aerodynamic-structure-propulsion integrated design can effectively improve aircraft performance. Especially in aircraft structure design, the structure of traditional aircraft uses a large amount of metal materials, which is heavy, poor in performance, opaque, and highly concentrated, which seriously limits the vision of personnel inside the aircraft. Therefore, based on the propulsion characteristics of electric aircraft, the design of a high-performance, pollution-free, low-cost, light-weight, and multi-transparent panoramic flight platform with a new overall design concept will further promote the development of electric aircraft.

[0004] Taking into account the aircraft's geometric parameters, aerodynamic parameters, weight parameters, power system parameters, structural strength, equipment maintenance channels, and division of the operating cabin and equipment cabin, we carried out sensitivity analysis and coordination of key parameters and designed a panoramic flight platform to improve the domestic development of this technology field. Summary of the invention

[0005] The purpose of the present invention is to design a high-performance, pollution-free, low-cost, light-weight, multi-transparent panoramic flying platform based on the propulsion characteristics of electric aircraft and adopting a new overall design concept.

[0006] The present invention is implemented by adopting the following technical scheme.

[0007] A panoramic flight platform, the panoramic flight platform is a tower-shaped structure with a flat upper surface, the middle part of the panoramic flight platform is a cylindrical hollow structure, and a coaxial double rotor is arranged in the cylindrical hollow structure to form a ducted coaxial double rotor;

[0008] The circumferential cross section of the panoramic flight platform is a regular polygon;

[0009] The panoramic flight platform body is made of transparent materials, and the remaining load-bearing structures are composed of extremely narrow structural frames.

[0010] Furthermore,

[0011] The outer circle of the panoramic flight platform is the cockpit and the passenger cabin. The 360° space of the outer circle is divided into two major areas: the cockpit and the passenger cabin. Transparent parts are used as windshields in front of the cockpit and the passenger cabin. The passenger cabin and the cockpit are separated by two left and right structural wall panels.

[0012] Furthermore,

[0013] There is a circle of circular seats arranged inside the cabin, and two levels of cabins are set up under the seats. The lower level is the power cabin of the flight platform, and the upper level is the equipment cabin of the flight platform.

[0014] Power batteries are arranged in the power cabin to provide energy for the ducted coaxial twin rotors;

[0015] The equipment cabin space is divided into three major blocks, which house the panoramic flight platform's flight control system, environmental control system and avionics system.

[0016] Furthermore,

[0017] Three universal landing gears and annular emergency buffer devices are installed at the bottom of the panoramic flight platform. In an emergency, the annular emergency buffer device will open and pop out a bowl-shaped buffer airbag downward to protect the flight platform and the people inside the aircraft.

[0018] Furthermore,

[0019] There are multiple navigation lights evenly arranged around the largest outline of the lower and middle part of the panoramic flight platform to serve as a warning of the outline of the panoramic flight platform. There are three lifting rings on the top of the panoramic flight platform to facilitate the lifting and movement of the panoramic flight platform.

[0020] Furthermore,

[0021] The panoramic flight platform has two flight modes: manned and unmanned;

[0022] There are two comprehensive display control panels on the left and right sides of the middle of the cockpit windshield. In manned driving mode, the panoramic flight platform is driven and operated through the comprehensive display control panels.

[0023] Furthermore,

[0024] When unmanned, the operation process of the panoramic flight platform is as follows:

[0025] Vertical takeoff: Start the power system, the ducted coaxial twin rotors provide lift, and the panoramic flight platform rises vertically to the preset height;

[0026] Forward flight state: The flight control system adjusts the flight attitude to tilt the panoramic flight platform to a preset small angle, providing forward flight power, and the panoramic flight platform maintains the forward flight state at the preset altitude;

[0027] Hovering state: The flight control system controls the panoramic flight platform to rotate 360 ​​degrees around the central axis;

[0028] Vertical landing: After reaching the destination, the flight control system adjusts the flight attitude to restore the panoramic flight platform to a horizontal attitude. The flight control system controls the ducted coaxial twin rotors to reduce the rotation speed, reduce lift, and descend for landing.

[0029] Furthermore,

[0030] Of the 360° space, 60° is the cockpit and the remaining 300° is the passenger cabin.

[0031] The technical solution of the present invention adopts a new overall design concept to design a high-performance, pollution-free, low-cost, light-weight, multi-transparent panoramic flight platform. As a low-altitude aircraft, it effectively solves the problems of traditional fuel aircraft such as heavy weight, high cost and poor vision in demand scenarios such as sightseeing and transportation.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0039] An embodiment of the present invention provides a panoramic flight platform, wherein the panoramic flight platform is a tower-shaped structure with a flat upper surface, the middle portion of the panoramic flight platform is a cylindrical hollow structure, and a coaxial double rotor is arranged in the cylindrical hollow structure to form a ducted coaxial double rotor;

[0040] The circumferential cross section of the panoramic flight platform is a regular polygon;

[0041] The panoramic flight platform body is made of transparent materials, and the remaining load-bearing structures are composed of extremely narrow structural frames.

[0042] The outer circle of the panoramic flight platform is the cockpit and the passenger cabin. The 360° space of the outer circle is divided into two major areas: the cockpit and the passenger cabin. Transparent parts are used as windshields in front of the cockpit and the passenger cabin. The passenger cabin and the cockpit are separated by two left and right structural wall panels.

[0043] There is a circle of circular seats arranged inside the cabin, and two levels of cabins are set up under the seats. The lower level is the power cabin of the flight platform, and the upper level is the equipment cabin of the flight platform.

[0044] Power batteries are arranged in the power cabin to provide energy for the ducted coaxial twin rotors;

[0045] The equipment cabin space is divided into three major blocks, which house the panoramic flight platform's flight control system, environmental control system and avionics system.

[0046] Three universal landing gears and annular emergency buffer devices are installed at the bottom of the panoramic flight platform. In an emergency, the annular emergency buffer device will open and pop out a bowl-shaped buffer airbag downward to protect the flight platform and the people inside the aircraft.

[0047] There are multiple navigation lights evenly arranged around the largest outline of the lower and middle part of the panoramic flight platform to serve as a warning of the outline of the panoramic flight platform. There are three lifting rings on the top of the panoramic flight platform to facilitate the lifting and movement of the panoramic flight platform.

[0048] The panoramic flight platform has two flight modes: manned and unmanned;

[0049] There are two comprehensive display control panels on the left and right sides of the middle of the cockpit windshield. In manned driving mode, the panoramic flight platform is driven and operated through the comprehensive display control panels.

[0050] When unmanned, the operation process of the panoramic flight platform is as follows:

[0051] Vertical takeoff: Start the power system, the ducted coaxial twin rotors provide lift, and the panoramic flight platform rises vertically to the preset height;

[0052] Forward flight state: The flight control system adjusts the flight attitude to tilt the panoramic flight platform to a preset small angle, providing forward flight power, and the panoramic flight platform maintains the forward flight state at the preset altitude;

[0053] Hovering state: The flight control system controls the panoramic flight platform to rotate 360 ​​degrees around the central axis;

[0054] Vertical landing: After reaching the destination, the flight control system adjusts the flight attitude to restore the panoramic flight platform to a horizontal attitude. The flight control system controls the ducted coaxial twin rotors to reduce the rotation speed, reduce lift, and descend for landing.

[0055] Of the 360° space, 60° is the cockpit and the remaining 300° is the passenger cabin.

[0056] Specifically,

[0057] The panoramic flight platform power system adopts a central layout. There is a rotor system in the center of the panoramic flight platform. The rotor system is a ducted coaxial twin rotor. Its power conversion control is simple, the electronic system is highly integrated, and the power-to-weight ratio parameters are excellent. In addition, the upper and lower rotors are inside the central structure, which can greatly improve the safety of the flight platform.

[0058] The outer circle of the central power system of the panoramic flight platform is the cockpit and the cabin. The 360° space of the outer circle is divided into two major areas: the cockpit and the cabin. 60° of the space is the cockpit, and the remaining 300° is the cabin. The cabin and the cockpit are separated by two structural wall panels on the left and right. The personnel entering and exiting between the cabin and the cockpit are blocked to prevent the cabin occupants from interfering with the driver.

[0059] The panoramic flight platform fuselage is made of transparent materials, and the rest is composed of an extremely narrow structural frame. The extremely narrow structural frame serves as the main load-bearing and load-transmitting structure, which can effectively ensure the strength of the flight platform. Most areas of the fuselage are made of flat transparent parts to avoid distortion of the exterior view and provide passengers in the aircraft with a 360° panoramic view.

[0060] The cockpit of the panoramic flight platform occupies a 60° space. The flight platform is designed with two flight modes: manned and unmanned. There is a huge transparent piece in front as a windshield. Two comprehensive display control panels are set on the left and right sides of the middle of the windshield. In the manned driving mode, the panoramic flight platform can be driven and operated through the comprehensive display control panel;

[0061] The cabin of the panoramic flight platform occupies a 300° space, and a circle of circular seats are arranged inside the cabin. There are two layers of cabins under the seats, the lower layer is the power cabin of the flight platform, and the upper layer is the equipment cabin of the flight platform.

[0062] Six large rectangular power batteries are arranged in the power cabin of the panoramic flight platform to provide energy for the rotor system. The equipment cabin of the panoramic flight platform is divided into three major blocks, which are respectively used to arrange the flight control system, environmental control system and avionics system of the flight platform.

[0063] When no one is driving:

[0064] Vertical takeoff: Start the power system, the ducted coaxial twin rotors provide lift, and the panoramic flight platform rises vertically to the preset height;

[0065] Forward flight state: The flight control system adjusts the flight attitude to tilt the panoramic flight platform to a preset small angle, providing forward flight power, and the panoramic flight platform maintains the forward flight state at the preset altitude;

[0066] Hovering state: The flight control system controls the panoramic flight platform to rotate 360 ​​degrees around the central axis;

[0067] Vertical landing: After reaching the destination, the flight control system adjusts the flight attitude to restore the panoramic flight platform to a horizontal attitude. The flight control system controls the ducted coaxial twin rotors to reduce the rotation speed, reduce lift, and descend for landing.

[0068] The panoramic flight platform is equipped with three universal landing gears and annular emergency buffer devices at the bottom. In an emergency, the emergency buffer device opens and pops out a bowl-shaped buffer airbag to protect the flight platform and the people inside. Six navigation lights are set around the largest outline of the lower middle part of the panoramic flight platform to serve as a warning of the flight platform outline. There are three lifting rings on the top of the panoramic flight platform to facilitate the lifting and movement of the platform.

[0069] A new overall design concept is adopted to design a high-performance, pollution-free, low-cost, light-weight, and multi-transparent panoramic flight platform. As a low-altitude aircraft, it effectively solves the problems of traditional fuel aircraft such as heavy weight, high cost, and poor vision in demand scenarios such as sightseeing and transportation.
