(g) Moisture and particulate separator systems which are capable of removing 99.9 per cent of particles larger than 2 micrometres in diameter with a maximum pressure loss of 1.6 kPa (16 millibar) for gas turbine engine air inlets
Note:
Technology control for the moisture and particulate separator systems covered by this sub-item above is limited to the following:
(1) Technology for preventing water leakage around the filter stages; and
(2) Technology for integrating the components of such a system.
(h) Specially designed components for vessels covered by sub-items (a), (b) and (c) above, as follows:
(1) Advanced hull forms which incorporate any of the following:
(i) Stepped hulls for hydrofoil vessels;
(ii) Hulls for air cushion vehicles with trapezoidal planforms;
(iii) Hulls for surface-effect vehicles with catamaran-like sidewalls;
(iv) Hulls for wing-in-ground effect vehicles;
(v) Underwater hulls and struts for SWATH vessels;
(2) Fully submerged subcavitating or supercavitating hydrofoils;
(3) Lightweight structural components for SWATH vessels, hydrofoil vessels and surface-effect vehicles, constructed using anisotropic, orthotropic or sandwich construction methods.
Technical Notes:

3.
Anisotropic construction methods relate to the use of fibre reinforcing members aligned so that the load-carrying ability of the structure can be primarily orientated in the direction of expected stress.
Orthotropic construction methods relate to means of stiffening plates, in which the structural members are at right angles to each other. Sandwich construction methods relate to the use of structural members or plates which are fabricated and permanently affixed in layers to enhance their strength and reduce their weight.
(4) Flexible skirts, seals and fingers for surface-effect vehicles;
(5) Systems for automatically controlling the stability of SWATH vessels, hydrofoil vessels or surface-effect vehicles;
(6) Power transmission/shaft systems which incorporate composite material components, for SWATH vessels, hydrofoil vessels or surface-effect vehicles;
(7) Lightweight, high capacity (K factor greater than 150) gearing (planetary, cross-connect and multiple input/output gears and bearings) for SWATH vessels, hydrofoil vessels and surface-effect vehicles;
Technical Note:
For the K factor, see AGMA tables of K factor values (based on tooth profile, pinion and gear materials and surface endurance limits).
(8) Water-cooled electrical propulsion machinery (motor and generator), including AC-AC synchronous and AC-DC systems, sectored-disc and concentric-drum rotors for DC homopolar machines, for SWATH vessels, hydrofoil vessels and surface-effect vehicles;
(9) Superconducting electrical propulsion machinery for SWATH vessels, hydrofoil vessels and surface-effect vehicles;
(10) Lift fans for surface-effect vehicles, rated at greater than 400 hp;
(11) Waterjet propulsor systems rated at 3,000 input hp or greater for hydrofoil vessels and surface-effect vehicles;
