A sabot petal is described herein comprising a plurality of woven axial and undulated fibers angled to transfer setback loads. In some cases, the petal is a one-piece component configured to be positioned around a long rod projectile or other aerostructures or aeroshell shapes to be launched with in a gun bore, or rocket or missile launch tube. Corresponding systems and methods are also disclosed.

B29C 70/24 - Fibrous reinforcements only characterised by the structure of fibrous reinforcements using fibres of substantial or continuous length oriented in at least three directions forming a three dimensional structure
B29C 70/68 - Shaping composites, i.e. plastics material comprising reinforcements, fillers or preformed parts, e.g. inserts by incorporating or moulding on preformed parts, e.g. inserts or layers
B29K 105/08 - Condition, form or state of moulded material containing reinforcements, fillers or inserts of continuous length, e.g. cords, rovings, mats, fabrics, strands or yarns
Sabots and riders are described herein that have high torsional stiffness, providing for utility in high-speed projectiles. The sabots include multiple petals with a closed configuration comprising polymer or metal containing composites. Corresponding systems and methods also are disclosed.
Disclosed herein is sabot for a sub-caliber projectile comprising a plurality of petals, such that a slip mechanism can be incorporated between the sabot petals and the pusher mechanism to decrease or prevent the sabot from rotating in a rifled gun bore, or the petals themselves can be separated into forward petals and aft petals, with only the aft petals rotating along with the gun rifle. When separate forward petals and aft petals are used, the torque transferred to the forward petals is greatly reduced, thus decreasing the angular rotation of the forward petals with the intent of preventing the forward petals from rotating. The slip mechanism has slip plates with low-coefficient of friction surfaces configured to contact adjacent slip plates prior to and during launch. As assembly, a system, and corresponding methods also are disclosed.
