Definitions

  • the present invention patent refers to a support ladder for aircraft, particularly used to facilitate the boarding and disembarking of passengers and crew in aircraft, such as helicopters or similar, so that the ladder is easily installed and removed , by a single user, and provides security and practicality for users.
  • the invention also deals with a system for storing and transporting support ladders for aircraft, so that the ladder is light and can be transported in a practical and efficient way, inside the aircraft itself.
  • Ladders for boarding and disembarking landed aircraft, specifically helicopters and the like, are known to those skilled in the art.
  • helicopters and other transport vehicles of the “VTOL - Vertical Take-Off and Landing” type which use their own propulsive means to take off, such as drones, cars or flying motorcycles, offer broad advantages over others. means of air transport with few passengers, as they allow passengers to travel over small and medium distances safely and practically, at a more attractive cost-benefit ratio than other air transport alternatives.
  • helicopters and other VTOL-type vehicles have the advantage of not requiring excessively spacious structures to take off or land, all you need is a small helipad for this. This fact has popularized the use of helicopters, especially in urban regions, where spaces are, by definition, more crowded.
  • Stairs are necessary, as it is, at the very least, uncomfortable and unsafe, or even unfeasible, depending on the conditions, to get on or off the aircraft without the aid of a ladder, due to the distance between the ground and the floor level or floor of the helicopter or other type of VTOL vehicle. This height is a natural result of the use of skis or landing pads on these aircraft.
  • both the take-off location and the landing location each have a staircase available. This does not always occur, as many routes that take advantage of the versatility of transport via aircraft have take-off and/or landing locations that are not appropriate places for the permanent storage of ladders, such as open fields, backyards, farms, rooftops, buildings, etc.
  • the present invention proposes a support ladder for aircraft and a support ladder storage and transport system for aircraft, which provides a compact and light ladder, extremely easy to handle and use, at the same time as it increases the safety of passengers and crew during boarding and disembarking from aircraft, offering excellent safety during use.
