Abrégé

A parasitic drag induced boundary layer reduction system and methods for reducing the boundary layer on aircraft, vehicles, and structure. The system may include a suction generator configured to utilize parasitic drag in reducing boundary layer effect and enhancing laminate flow. The suction generator may include at least one of a suction port on a rearward facing surface of an aircraft, a suction vane on each wing of the aircraft, a wingtip vane on each wing of the aircraft, and a slotted tail section on a tail of the aircraft. The system may also include an induction structure configured to introduce airflow to suction created by the suction generator as the aircraft is in flight.

Classes IPC  ?

• B64C 21/06 - Moyens permettant d'influencer l'écoulement d'air sur les surfaces des aéronefs en agissant sur la couche limite par utilisation de fentes, de conduits, de surfaces poreuses ou de dispositifs similaires en vue de l'aspiration

A non-metallic armor article comprises a pultruded housing defining at least one cavity. A plurality of substantially dry ballistic impact resistant broad goods sheets are at least partially enclosed in the cavity and held in suspension independently within the cavity. The pultruded housing is engaged with the plurality of substantially dry ballistic impact resistant broad goods sheets by being secured to one or more of the plurality of substantially dry ballistic impact resistant broad goods sheets.

A system and method for stabilizing an incontinent cervix during pregnancy are described. A system may include a nesting portion designed to surround the cervix without applying pressure to the cervix, while supporting the uterus in opposition to the weight of the developing fetus to prevent untimely effacement and dilatation of the cervix; thereby reducing the risk of premature birth and its consequence.
