Abstract
The invention offers a novel way to enhance the time of a surveillance paad over a target area. It provides a relatively inexpensive way to position an unmanned reconnaissance payload over a potential target area, using a cargo projectile launched from a conventional tubed artillery piece, under all weather and environmental conditions. The use of tow line between the ejected reconnaissance payload and the ballistic cargo projectile allow the payload with its parafoil to achieve a greater height, enter an orbit and extend a longer time over the target area.
Claims4
An unmanned reconnaissance device which can be launched from conventional cannon artillery, and which device has an extended altitude feature, making available an extended time for reconnaissance of an area which is under surveillance, said device comprising:
- a projectile having a surveillance cargo which comprises a reconnaissance payload suspended from a parafoil in which said parafoil includes a drogue chute, said chute being connected to said projectile by a line means, said projectile having means to eject said surveillance cargo from said projectile, said means to eject being initiated during flight by a preset fuze which initiates said ejection when said projectile is essentially at the highest point of its trajectory by releasing said drogue chute, and said drogue chute thereafter acting to pull out said parafoil which has attached thereto said reconnaissance payload, said parafoil also being attached to said line means to maintain its connection to said projectile, whereby said extended altitude feature is achieved inasmuch as said reconnaissance payload after ejection can reach an altitude higher than that of said projectile altitude, while still attached to said line means, through a kite-like action of the parafoil rising higher than said projectile, and said reconnaissance payload being suspended from said parafoil thereby also rising higher than said projectile.
