A tail skid shock absorber including an outer shock absorber canister, a crushable indicator cartridge disposed within the outer shock absorber canister, and an indicator rod coupled to the crushable indicator cartridge so as to move with a portion of the crushable indicator cartridge as a unit.

A tail skid shock absorber including an outer shock absorber canister, a crushable indicator cartridge disposed within the outer shock absorber canister, and an indicator rod coupled to the crushable indicator cartridge so as to move with a portion of the crushable indicator cartridge as a unit.

A tie-down for attachment to an aft tail section of an aircraft for inhibiting damage to the aircraft when the aircraft is on the ground is disclosed. The tie-down has a mount member configured to attach to the aft tail section and a projection member supported by the mount member. The projection member extends in a generally downward direction from the mount member so as to provide a contact surface with the ground that is lower than the aft tail section.

A tail skid shock absorber including an outer shock absorber canister, a crushable indicator cartridge disposed within the outer shock absorber canister, and an indicator rod coupled to the crushable indicator cartridge so as to move with a portion of the crushable indicator cartridge as a unit.

A wedge frame for an aircraft that provides tailstrike angle enhancement. The wedge frame has converging, non-parallel faceplanes that tilt a rear portion of the aircraft fuselage upward in order to prevent or reduce risk of the tail of the aircraft striking the ground during takeoff and landing. A method to prevent or reduce risk of the rear portion of an aircraft from striking the ground during takeoff and landing by using a wedge frame having converging, non-parallel faceplanes to tilt upward the rear portion of the aircraft.

A system includes an aircraft having a fuselage with a tail portion. A tail skid is disposed in an opening of the tail portion. The tail skid includes a ground contact shoe and a mechanism configured to selectably move the ground contact shoe between respective ones of a stow position disposed within the opening, a landing position disposed below the opening, and a takeoff position different than the stow and landing positions. Before a takeoff or a landing, the ground contact shoe is moved to a corresponding one of the takeoff or landing positions. In the event of an over-rotation or an over-flaring of the aircraft during a takeoff or a landing, respectively, the ground contact shoe makes contact with the ground and a shock absorber of the system absorbs a shock of the contact and thereby prevents tail strike damage to the aircraft.

Tail strike mitigation devices and related methods are disclosed herein that can prevent or mitigate a tail of an aircraft from striking a runway surface when landing or taking off, including when landing on or taking off from a semi-prepared runway. Tail strike mitigation devices of the present disclosure can extend, for example, from a bottom surface of the fuselage of the aircraft at a tail of an aircraft and/or can include a tail skid with a large contact surface area, as compared to conventional tail strike devices. The tail skid can have a high flotation impact surface. The tail skid can be moved between retracted and deployed positions, and can be oriented at a range of angle relative to at least one of the landing surface and/or the bottom surface of the fuselage.

An attachment system for fastening an element to an aircraft fuselage, wherein the attachment system has a plate having a first face and a second face oriented towards the fuselage, and wherein the plate is fastened to the fuselage, a fitting fastened to the element and having a contact face in contact with the first face, and at least one fastening bolt having a screw and a nut, wherein the head of the screw is housed in the plate on the side of the second face, and wherein the nut is screwed to the screw, sandwiching the plate and the fitting. Also an aircraft with such an attachment system.

An energy absorbing rub strip having a core material and a fairing positioned over the core material. The core material may be configured to buckle under the application of a predetermined amount of force and the fairing may be configured to be attached to a fuselage of an aircraft. The fairing may be made out of an abrasive-resistant material such as titanium or a nickel-based metal. The core material may be comprised of an aluminum honeycomb. The core material may be comprised of a dual density material. The length of the rub strip may extend beyond potential contact points on the fuselage during landing and takeoff. Upon a ground contact event, the thickness of deformed/buckled core material may be measured to determine if the ground contact event may have caused structural damage to the aircraft.
