Description

Inventors name: Timothy Dove 1 Name of invention: Flight safety line and modification of single and multirotor u.a.v. body Abstract of specification: This invention is a safety device for a remote controlled single or multirotor unmanned aerial vehicle that includes a modification of the body.
The modification is to the main body and consist of a thru-hole in the main body including appendages and attachments to the main body, providing containment of the flight safety line .The introduction of a cord or line (flight safety line) that has a spring attached to the upper supported end, running through the provided thru-hole of the body and/ or attachments, weighted and secured at the base end and termination point. As a result a safety aspect is providing by a predictable flight path and restraining of the multirotor u.a.v. for the embodiment of this invention. By mounting a camera and/or other scanning equipment, the application of this invention allows the remote controlled piloted multirotor aircraft to be deployed as a building inspection device that has a dedicated flight path. In addition the invention aids in Flight training of multirotor U.A.V , aerial filming as well as to reduce hazards where Aviation safety is paramount. The integration of the singte or multiple flight safety line through the aperture of the body and appendages of the single or multirotor unmanned aerial vehicle restricts the flight mission to a localized space.
Description Name: Flight safety line and modified single and multirotor u.a.v.
body In response to the Ministry of Transportation concerns with Aviation Safety and the remote controlled aircraft (u.a.v) this invention addresses the autonomous and piloted operation of model aircraft. This system and device has evolved so to reduce hazards such as Fly away, lost link jeopardy, falling location. The flight safety line restricts flight to a vertical or angular trajectory. For Building inspection, roof top rigging is achieved by standard rigging equipment and techniques. In the event of the failure of the aircraft or pilot error, the remote controlled single or multirotor u.a.v. has the potential to be recovered in flight and/or land at the base of the Flight safety line, where a energy absorbing landing zone (air bag) with protective barriers may be located. The Flight Safety line influences the freedom of movement of the remote controlled single or multirotor uav and defeats or restricts flight to within the deflection and vertical axis of the flight safety line. The upper supported end has a spring attachment at the upper end of the line, then anchored or shackled to the supporting member.
Running through the multirotor u.a.v. body, the line is then terminated at the base where the Flight safety line is weighted and /or secured. List of figures contained herein:1(1a,1b,1c,1d) A,A1,A2(abLab2,ab3,ab4,ab5,ab6)C1(c2,c3,c4,c5,c6) D1(d2,d3,d4)

2 1 Flight safety line can be made of varying materials and diameters, examples:
rope, cable, carbon fiber thin line, nylon, polyester depending on the requirements and the diameter of the thru-hole aperture and containment space required.
2 In the first instance the Flight safety Line is threaded through the main body of the single or multirotor u.a.v. The open space of the thru- hole that is perpendicular to the plain of the body, central and balanced member including the appendage members. Ipso facto causing the main body to be captivated and restrained. As a result the body is restricted to operating within the circumference space of the thru- hole diameter and or the appendages thru- hole space.

3 The access path cut out of the main body allows the flight safety line to traverse the plain of the body, enter into and is contained by the (abl-ab6) restraining mechanism or retainer part.
Allowing the body of the aircraft to engage and/or disengage the Flight safety Line as it remains shackled and secured.
The said application enables the flight path of the remote control uav to be predictable with safety attribute as well as assist in flight operations in a windy environment. Environmental weather considerations may require additional flight safety lines to maintain flight and stability.
Regardless if the propellers are (7)caged or not, the placement of aperture clearance guides are such that they would not interfere with the flight safety lines that pass through the body or appendage .To be placed outside the circumference of the Propeller blades.
The invention is in the application of a suspended line or multiple lines that pass through the modified body and appendages of a remote controlled single or multirotor unmanned aerial vehicle, including the modification by the aperture through the body and its appendages, as well as the cut away access path with retainer. a(3-3) gate latch type Is required where the flight safety line has been secured to the base.
#5 and#6 have variable dimensions of the clearance guide. Internal diameter can be variable in size. This appendage is an alternative to the modification of the body aperture. Access provided by the removal, opening up of the ring and re attach to the main body, a(6-1) gate latch type is required where the flight safety line has been secured to the base.
The #5 appendage is intrinsically connected with the thru- hole application, member 5 is attached and exterior to the main body. Allowing it to be engaging or disengaging to the main body. This member is included as a appendage attachment.

Description : Flight safety line and engagement device of U.A.V body The known multi rotor U.A.V Drone consists of:1 or more motors, propellers,wiring,electrical signal controller ,power distribution board, flight controller,transmitter and receiver,energy source and frame or body, deployed to fly in multi-directional airspace,according to the signals or instructions by the operator or autonomously controlled piloting. The invention is the access (21) and closure device(22) allowing captivation of the line,rope,string,cable,cord, static line or flight safety line(12), singular(12) or plural(14).
Made of traditional materials. The invention addresses the autonomous and piloted operation of model aircraft.
The invention possesses numerous benefits and advantages over known said U.A.V flight dynamics. Flight is limited to the length and direction of the static line. This system and device has evolved to reduce hazards such as fly away, lost link jeopardy,falling location.
The invention provides a solution to accessing(21) and retaining(22) a static line as a system. The said U.A.V. system is applied where people are at risk of falling including locations where inspecting components of structures are difficult to access. The invention provides a alternative way to safely inspect and collect data in situ.
pg3 The said static line restricts flight to a vertical(12),angular(27) or horizontal (25) trajectory,following the axis in parallel and orbiting of the said static line. For building inspection,roof top rigging is achieved by standard rigging equipment and techniques. In the event of failure of the aircraft or pilot error,the said U.A.V. has the potential to be recovered in flight or land at base where air bags(13) are located. The said static line influences the freedom of movement of the said U.A.V. that defeats or restricts flight to within the deflection and axis of the said static line. A integrated system, internally encompassing a static line and restricted by the same static line. The upper supported end having a spring attachment(11) then anchored or shackled to the supporting member(10) one end of the said static safety line. (12) Continue running through (15) the said U.A.V. Body(9) and retained by captivation device.(22)(23 ) The line is then terminated at the base end where the static line is then weighted,shackled,staked or secured.(I3 ) Terminated end may only require a stop for some applications of inspecting structures.
