Abstract
According to a first aspect of the invention, there is provided an object for moving through a fluid, the object comprising: an outer housing, arranged to be exposed to a hydrostatic pressure exerted by the fluid; a strain gauge, arranged to obtain an indication of the hydrostatic pressure, wherein a first part of the strain gauge is arranged to be in contact with the outer housing, such that the strain gauge is arranged to obtain an indication of the hydrostatic pressure by obtaining an indication of the strain on the housing.
Claims20
A projectile comprising:
- a carrier having a cavity and configured to be launched, into the air, from a gun barrel;
- and
- a submunition arranged within the cavity of the carrier and configured to be controllably expelled from the carrier prior to entering a body of water, wherein the submunition comprises
- a housing, arranged to be exposed to a hydrostatic pressure exerted by the water;
- and
- a strain gauge, arranged to obtain an indication of the hydrostatic pressure, wherein at least a part of the strain gauge is arranged to be in contact with the housing, such that the strain gauge is arranged to obtain an indication of the hydrostatic pressure by obtaining an indication of the strain on the housing.
A method of obtaining an indication of a hydrostatic pressure on a submunition of a projectile, the method comprising:
- launching the projectile, into the air, from a gun barrel;
- controllably expelling the submunition from a remainder of the projectile prior to the submunition entering a body of water;
- and
- obtaining the indication of the hydrostatic pressure exerted by the water on a housing of the submunition by obtaining an indication of a strain on the housing using at least part of a strain gauge in contact with the housing.
