Multifunction aerodynamic housing for ballistic launch of a payload

1. A projectile comprising a payload and an aerodynamic outer housing, wherein:

(a) the outer housing is arranged, in launch and flight configurations, to surround the payload;

(b) the outer housing is further arranged, in the launch configuration, to be launched from a barrel of a launching gun or cannon;

(c) the outer housing is further arranged, in the flight configuration, to have a bi-tapered shape that is elongated along a fore-and-aft direction and has a longitudinal profile that tapers in both fore and aft directions;

(d) the outer housing is arranged to assume an exoatmospheric configuration upon reaching a target distance-from-launch, a target time-from-launch, a target altitude, or a target velocity;

(e) in the exoatmospheric configuration, either (i) the outer housing is arranged to release the payload or (ii) the outer housing and payload are arranged in a propulsion configuration;

the outer housing is arranged to transition from the launch configuration to the flight configuration upon the projectile exiting the barrel; and

an aft portion of the outer housing is collapsible, the aft portion of the housing is collapsed in the launch configuration, and the aft portion of the housing is extended in the flight configuration.

2. A projectile comprising a payload and an aerodynamic outer housing, wherein:

(a) the outer housing is arranged, in launch and flight configurations, to surround the payload;

(b) the outer housing is further arranged, in the launch configuration, to be launched from a barrel of a launching gun or cannon;

(c) the outer housing is further arranged, in the flight configuration, to have a bi-tapered shape that is elongated along a fore-and-aft direction and has a longitudinal profile that tapers in both fore and aft directions;

(d) the outer housing is arranged to assume an exoatmospheric configuration upon reaching a target distance-from-launch, a target time-from-launch, a target altitude, or a target velocity;

(e) in the exoatmospheric configuration, either (i) the outer housing is arranged to release the payload or (ii) the outer housing and payload are arranged in a propulsion configuration;

in the exoatmospheric configuration, the outer housing and payload are arranged in the propulsion configuration; and

in the propulsion configuration, an aft portion of the outer housing that is rearward-tapered in the flight configuration is arranged antiparallel to that arrangement and so is forward-tapered.

3. The projectile of claim 2 wherein the forward-tapered rearward portion of the outer housing acts as at least a portion of a rocket motor.

4. A projectile comprising a payload and an aerodynamic outer housing, wherein:

(a) the outer housing is arranged, in launch and flight configurations, to surround the payload;

(b) the outer housing is further arranged, in the launch configuration, to be launched from a barrel of a launching gun or cannon;

(c) the outer housing is further arranged, in the flight configuration, to have a bi-tapered shape that is elongated along a fore-and-aft direction and has a longitudinal profile that tapers in both fore and aft directions;

(d) the outer housing is arranged to assume an exoatmospheric configuration upon reaching a target distance-from-launch, a target time-from-launch, a target altitude, or a target velocity;

(e) in the exoatmospheric configuration, either (i) the outer housing is arranged to release the payload or (ii) the outer housing and payload are arranged in a propulsion configuration;

in the exoatmospheric configuration, the outer housing and payload are arranged in the propulsion configuration; and

in the propulsion configuration, an aft portion of the outer housing that is rearward-tapered in the flight configuration is positioned at a forward end of the projectile.

5. The projectile of claim 4 wherein forward-positioned aft portion of the outer housing contains fuel or propellant, imaging components, instrumentation, equipment, or stored objects or material.

6. A method comprising:

(a) loading a projectile into a barrel of a launching gun or cannon;

(b) after loading the projectile and before launching the projectile, lowering the gun barrel into a casing-lined bore hole and filling at least a portion of a volume of the bore hole outside the gun barrel with drilling mud; and

(c) launching the projectile from the barrel of the launching gun or cannon, wherein:

(d) the projectile comprises a payload and an aerodynamic outer housing;

(e) the outer housing is arranged, in launch and flight configurations, to surround the payload;

(f) the outer housing is further arranged, in the launch configuration, to be launched from a barrel of a launching gun or cannon;

(g) the outer housing is further arranged, in the flight configuration, to have a bi-tapered shape that is elongated along a fore-and-aft direction and has a longitudinal profile that tapers in both fore and aft directions;

(h) the outer housing is arranged to assume an exoatmospheric configuration upon reaching a target distance-from-launch, a target time-from-launch, a target altitude, or a target velocity; and

(i) in the exoatmospheric configuration, either (i) the outer housing is arranged to release the payload or (ii) the outer housing and payload are arranged in a propulsion configuration.

7. The method of claim 6 further comprising, after launching the projectile, removing the barrel from the casing-lined bore hole.
