TAKEOFF-AND-LANDING COMPLEX FOR GROUND-EFFECT CRAFT AND METHOD OF PERFORMING TAKEOFF AND LANDING OF SUCH CRAFT Russian patent published in 2005 - IPC

FIELD: building ground-effect craft and takeoff-and-landing complexes for such craft with the use of static air cushion.

SUBSTANCE: proposed complex includes pusher-type propeller for horizontal thrust which embraces tail section of fuselage. Screw propeller of ground-effect craft is embraced by ring-shaped fairwater and is provided with engine mounted in tail section of fuselage. Ground-effect craft is provided with hermetic center-wing section and hermetic longitudinal beams mounted on peripheral ends of center-wing section. Inflatable shock-absorbing balloons are mounted in lower portion of longitudinal beams. Complex is also provided with units for forming static air cushion under center-wing section. Method of takeoff and landing of ground-effect craft consists in maintenance of excessive pressure in shock-absorbing balloons under longitudinal beams on sides of center-wing section; front and rear retractable guides of air cushion are placed in working position; swivel door is shifted from air duct shutoff position to position at angle relative to upper surface of center-wing section corresponding to 10-15% of air offtake flow created by air propeller at takeoff and landing modes, thus forming air intake for this part of air flow; part of air flow is transported to space for forming air cushion under front part of center-wing section behind front flexible guard and creating excessive static pressure of air.

EFFECT: improved flight and technical characteristics of ground-effect craft.
