Abstract
A switch key tool for setting the pulse repetition frequency code on a laser guided bomb. The switch key tool allows the user to set the pulse repetition frequency code when the laser guided bomb has its switch knobs and also when the laser guided bomb is missing its switch knobs.
Claims15
A switch key tool for setting a pulse repetition frequency (PRF) code for a laser guided bomb, said laser guided bomb having a plurality of switch knobs to set said PRF code which has a plurality of PRF code bits, said switch knobs setting the plurality of PRF code bits for said PRF code, said switch key tool comprising:
- (a) a cylindrical shaped body having a dark colored surface;
- (b) a rectangular shaped member affixed to one end of said cylindrical shaped member, said rectangular shaped member allowing a user to set each of said plurality of switch knobs by inserting said rectangular shaped member into an elongated slot within each of said switch knobs and rotating said switch key tool to aligned with one of a plurality of PRF code numbers located on the surface of said laser guided bomb, said PRF code numbers being representative of the PRF code bits for said PRF code;
- (c) a D-shaped opening positioned at the other end of said cylindrical shaped member, said D-shaped opening allowing a user to set a switch knob shaft for a switch knob which is disconnected and missing from said laser guided bomb by sliding the D-shaped opening over said switch knob shaft and rotating said switch key tool to align with another of said plurality of PRF code numbers;
- and
- (d) a pair of light colored identification lines formed within said cylindrical shaped body, one of said pair of light colored identification lines being positioned at each end of said cylindrical shaped body, said pair of light colored identification lines allowing a user to align said switch key tool with each of said plurality of PRF code numbers and thereby enter said PRF code into said laser guided bomb.
A switch key tool for setting a pulse repetition frequency (PRF) code for a laser guided bomb, said laser guided bomb having a plurality of switch knobs to set said PRF code which has a plurality of PRF code bits, said switch knobs setting the plurality of PRF code bits for said PRF code, said switch key tool comprising:
- (a) a cylindrical shaped body having a black surface;
- (b) a rectangular shaped member affixed to one end of said cylindrical shaped member, said rectangular shaped member allowing a user to set each of said plurality of switch knobs by inserting said rectangular shaped member into an elongated slot within each of said switch knobs and rotating said switch key tool to aligned with one of a plurality of PRF code numbers located on the surface of said laser guided bomb, said PRF code numbers being representative of the PRF code bits for said PRF code;
- (c) a D-shaped opening positioned at the other end of said cylindrical shaped member, said D-shaped opening allowing a user to set a switch knob shaft for a switch knob which is disconnected and missing from said laser guided bomb by sliding the D-shaped opening over said switch knob shaft and rotating said switch key tool to align with another of said plurality of PRF code numbers;
- (d) a pair of white identification lines formed within said cylindrical shaped body, one of said pair of white identification lines being positioned at each end of said cylindrical shaped body, said pair of white identification lines allowing a user to align said switch key tool with each of said plurality of PRF code numbers and thereby enter said PRF code into said laser guided bomb;
- and
- (e) a U shaped handle affixed to said cylindrical shaped body;
- (f) wherein said cylindrical shaped body and said rectangular shaped member are fabricated from aluminum.
A method for setting a pulse repetition frequency (PRF) code for a laser guided bomb having a plurality of switch knobs by utilizing a switch key tool comprising the steps of:
- (a) inserting a rectangular shaped member positioned at one end of said switch key tool into an elongated slot within each of said switch knobs;
- (b) rotating said switch key tool to align with one PRF code number of a plurality of PRF code numbers located on the surface of said laser guided bomb at the periphery of each of said switch knobs, said PRF code numbers being representative of PRF code bits for said PRF code;
- (c) aligning a first identification line included within said switch key tool with said one PRF code number for each of said switch knobs to enter said PRF code into said laser guided bomb;
- (d) sliding a D-shaped opening positioned at an opposite end of said switch key tool over a switch knob shaft for a switch knob which is disconnected and missing from said laser guided bomb;
- (e) rotating said switch key tool to align with another PRF code number of said plurality of PRF code numbers;
- and
- (f) aligning a second identification line included within said switch key tool with said another PRF code number to enter said PRF code number for said switch knob which is disconnected and missing from said laser guided bomb.
