Abstract
A rocket-fired visual signalling apparatus and method includes a rocket, an elongated streamer having a first end portion connected to the rocket and a rocket launcher for launching the rocket so that the rocket pulls the streamer into the air such that when the rocket burns out, the streamer is spread out over the surrounding ground cover to facilitate visibility of the streamer.
Claims27
A visual signalling apparatus comprising:
- a) a rocket having a rocket motor for producing discharged gases for propelling said rocket to produce thrustual momentum in said rocket;
- b) an elongated streamer having a first end portion connected to said rocket and a second end portion free of said rocket;
- and
- c) a rocket launcher cooperating with said discharged gases for imparting ballistic momentum to said rocket while said rocket is in said launcher so that said rocket extends said streamer as said rocket ascends, by dragging the first end portion of said streamer aloft while said second end portion remains free of said rocket.
1 more element
A method of visual signalling, the method including the steps of:
- a) producing a rapid discharge of gases from a rocket motor on a rocket inside a rocket launcher such that said discharge of gases cooperates with said rocket launcher to impart ballistic momentum to said rocket;
- b) maintaining said discharge for a period of time to produce thrustual momentum in said rocket to carry said rocket aloft while dragging a first end portion of a streamer attached to said rocket into the air while a second end portion of said streamer remains free such that said streamer is carried aloft and spread out for visibility.
