The capture nose on the Goose round. The Goose round with a capture bay in the nose: the same tube and magazine, a mechanical release, and a target brought down intact.
Encapsulator CS-111 changes the nose and nothing behind it. The figures below size the launch load and the capture event; the cards say why a buyer who needs what was overhead recovered whole would load it.
The capture round matches the kinetic round's mass, bore, exit velocity and magazine pitch, so it rides the same tube and indexes in the same magazine.
The designed effect is rotor fouling, and the designed outcome is an aircraft brought down intact and recoverable, so what was overhead can be examined, traced and attributed.
Every capture path the design carries is non-energetic, and where an airbag-style gas generant would deploy faster, the design declines it. There is no pyrotechnic anywhere in the round or in the launch chain that throws it.
The launcher lays the shot from a cue, a person arms it, and a partner's cue is a permissive that can never bypass the interlock chain.

Encapsulator CS-111 is a nose variant on the Goose line, not a new airframe. Everything from the tail fins forward to the nose bulkhead is Goose CS-110, unchanged; everything forward of it is new.
That boundary is the whole architectural idea. The launcher, the magazine, the ballistics and the guidance were paid for by the kinetic round, and the capture round inherits them rather than repeating them. What is new is the nose bulkhead and the bay in front of it: a stored energy source, the capture medium, a dispersal head and a mechanical release.
Four figures are held identical to CS-110 on purpose: the 1.6 kg all-up mass, the Ø90 mm bore, the ~189 m/s exit and the magazine pitch. With those held, the capture round matches the kinetic round's external envelope, mass and indexing features, and the two index side by side in one magazine. The choice of effect moves from procurement to the breech.
Everything new on the round sits forward of the nose bulkhead, in a bay built around four elements that stay the same whatever capture medium is packed into it.
The nose bulkhead carries the payload's inertial load into the hull sidewall rather than into the dispersal head, so the launch cannot press the payload into its own release.
Compressed gas, or a compressed spring stack, held until the release lets it go.
Packed or contained in the bay. The timing arithmetic rules free-expanding chemistry out as the primary medium.
The head decides whether the capture medium opens into a useful curtain or a useless knot.
A positive mechanical action that holds the bay shut through the launch stroke and needs no electrical power aboard to open.
Whatever is packed into the bay is accelerated by the same stroke as the round: about 607 g averaged over the stroke, and 1,159 g at the peak, which every head must survive.
| Quantity | Figure | Basis |
|---|---|---|
| Average launch acceleration | ~5,953 m/s², ~607 g | 189²/(2 × 3.0), over the stroke |
| Peak launch shock | 1,159 g | At the start of the stroke, all heads |
| Self-pressure at the base of a 180 mm liquid column | ~11.8 bar | ρ·a·h at about 1.1 g/cm³ |
A threshold release would have to be rated above the pressure the payload reaches during the stroke, then driven past it milliseconds later inside a round with no electrical power. The release is a positive mechanical action instead, such as a latch or a collapsing nose.
Canadian Shield does not build fuzes. The mechanism at the front of CS-111 is a standoff release, or deployment trigger: it opens a bay, and there is nothing aboard for it to initiate.
An unpowered round carries no battery, so an active proximity sensor is not available without putting back the electronics the design removed. That leaves releases that are mechanical from end to end. The collapse trigger is the mechanism the capture noses share: the nose collapses mechanically on contact, and the collapse itself releases the net or canopy, with no initiator and no electrical path.
The payload has to be deployed before the round arrives, and the time available is set by the standoff and the closing speed. Head-on against a 3 kg multirotor, the design case is about 200 m/s.
| Release standoff | Time to the target |
|---|---|
| At contact | 0 ms |
| 1 m | 5.0 ms |
| 5 m | 25 ms |
| 20 m | 100 ms |
Commercial two-part expanding chemistries work on cream times of 5 to 15 s, between one thousand and three thousand times too slow at a metre, and there is no standoff at which such a foam both expands in time and is still where the target will be. Filling a 12 L envelope in 5 ms takes about 2,400 L/s, the rate class of an automotive airbag. Airbags reach it with a pyrotechnic gas generant, which the carriers-not-munitions line rules out; the design arithmetic finds that stored cold gas can reach it without one.
The capture nose does not wrap a whole airframe. It fouls one or two rotors and unbalances the disc, and that is still a capture.
Wrapping even a small multirotor whole takes far more mass than the bay can carry, so the effect the round is designed for is rotor fouling: the capture medium goes into the disc, the disc loses its balance and the aircraft comes down. On a small multirotor one or two fouled rotors are enough. The capture medium has to be in the disc rather than near it.
The mission ends with the target intact and recoverable. The airframe, and whatever it was carrying, can be examined, traced and attributed. A fouled airframe still falls, a round that misses still comes down on its arc, and human safety comes first on the ground beneath both.
No warhead, fuze, primer, propellant, gas generant or initiator, in the round or in the magazine.
The aircraft comes down whole, so what was overhead can be traced and attributed.
Collision where collision is the right answer; capture where the airframe should come down in one piece.
The environmental design case is −30 °C. A steel nose does not notice the cold; stored energy, a packed capture medium and a release that has to move inside milliseconds do.
Gas output, seal compliance and the stiffness of a packed textile all move with temperature, and so would the cure of any post-contact adhesive. Each is carried at the design case rather than at room temperature, because a capability that only works above freezing is not a product for this ground.
The kinetic round needs nothing after the muzzle. For the capture round the recommended primary tier is Tier 2: a fibre paid out of the tube, with a person in the loop.
A preset round flies the arc it was given and cannot see a moving target, and the systems engineering recommends the fibre tier for the capture round for that reason.
Holding mass, bore, exit velocity and magazine pitch identical lets a magazine index both rounds, and leaves the choice of effect to each shot.
