SA114350628B1 - A payload carrying step platform - Google Patents

Abstract

The present invention essentially relates to a step platform (1) which is designed to be used in the helicopters (H), enables the pilot and passenger to enter and exit the cockpit of the helicopter easily and allows the payloads (F) to be carried safely. Besides, it relates to a fairing (8) which covers the payload (F) and reduces possible aerodynamic performance losses caused by protruding structure.

Description

1 load carrying an included platform

A payload carrying step platform Full Description Background The invention Jal relates to a step platform for an aerodynamic dual-function cockpit operating as a step using The mount place of the saa cockpit step on the helicopter body © enables the integration of payloads that are mounted on the outer side of the helicopter. The current vertical helicopters; there are many electronic system devices fas installed on them so that there is not enough space AK ja to place the payloads in the avionics compartment of the helicopters 0 All flight equipment 161100018 such as pilot interface units and avionics should be placed in the front section and for this reason; sale) should be arranged rearrangement in Avionics compartment With the helicopter to incorporate new devices Knowing the fact that the helicopter has a specific weight/balance 1 8110 and ccable length limitations Some problems are encountered when installing new equipment new equipment and sale) arrangement is necessary. due to lack of space in the avionics room”; The extra equipment requires it to be placed on the outside of the helicopter body and to achieve this task the aerodynamic structure by must be built outside the helicopter 00 body. The newly built space that emerges shall be outside the hull of the vertical raft; Structurally strong enough to withstand the rigors of vertical helicopter flight. The studies of F

— since the Finite element method studies that the surface of the vertical raft and the connecting members that carry the load allay to be sie so that it can withstand the flight conditions and to combine that installation cand) A must be the current cabin class. Since the flight cabin degree is still necessary to enter and exit the cockpit of a vertical helicopter, this function is configured in the new installation. US patent document EY 477705 discloses; Known application in (all Alla) climbing equipment for vehicles The ladder used in vehicles consists of flexible support members and steps of 5 m 518. Support limbs have 0 107905615 supports reinforcements to prevent bending 5600109 in opposite direction opposite .direction US Patent No. (Yo) VYYAVY Describes a "Known State of the Art" Application of a Folding Step Ladder Mountable on Wheels Tractor tire—.mountable rides a portable, foldable step ladder in a deployed configuration straddles ctruck, tractor, or other heavy vehicles It allows the operator and the mechanic to easily climb towards the engine room compartment 609106. With this, the ladder has one rung above the tire wheels and there are two lie rungs primarily connected to the foldable structures. The general description of the invention is The object of the present invention is to provide a step platform incorporated where The pilot and the passenger were able to enter and exit the cockpit of the vertical helicopter. Lad is structurally strong and allows integration of unit(s). F
