A retractable runway edge sheave for use in an aircraft arresting system. The arresting system functions to extend a cable across a runway for capture by a tailhook of an aircraft. The retractable runway edge sheave is designed to raise and lower the cable. The disclosed system may also feature a ramping system.
An arresting cable retraction mechanism for use across an aircraft runway. The retraction mechanism functions to extend a cable across a runway (for capture by a tailhook of an aircraft) without causing the cable to recede below the runway surface during an aircraft rollover/deflection event. The arresting cable retraction mechanism is also designed to help prevent damage to a retraction motion actuator due to high speed aircraft rollover. The disclosed system separates components related to retraction vs. deflection due to rollover, such that rollover events do not affect or load the motion actuator used for retraction.

Embodiments relate to aircraft arresting systems that use a net or a cable that extends across a section of a runway. Ends of the net or cable are secured to an elongated tape, which is secured to and forms a part of an energy absorbing brake system. The elongated tape is secured around a tape reel and is allowed to reel out (or "pay out") once the aircraft is engaged. Described is a system (10) for adjusting the height of the tape such that its elevation can be altered between the point at which it leaves the energy absorbing brake system and when it reaches the aircraft runway.

Embodiments of the present invention provide improvements to UAV launching systems. The disclosed launching system eliminates the use of hydraulic fluid and compressed nitrogen or air by providing an electric motor-driven tape that causes movement of a shuttle along a launcher rail. The shuttle is detachable from the motor-driven tape, such that stoppage of the tape can be separate from stoppage of the shuttle. Embodiments further provide a secondary arrestment strap. Further embodiments provide an anti-rollback latch system.
Systems and methods for providing aircraft braking signal alerts for aircraft are described including a first braking condition signal generated by a first aircraft (12) or a control station (16). The first braking condition signal may include, for example, a timestamp, an airfield identifier, a runway identifier, and/or first braking condition information. A runway to be used by a second aircraft (14) may be determined automatically, and a determination made regarding the relevance of the first braking condition information to the second aircraft. A braking alert signal for the second aircraft may be generated and/or updated based on the first braking condition information, and a visual indicator (7) may be presented to an operator of the second aircraft based on the braking alert signal. The first braking condition information may be overwritten based on a second braking condition signal received from a third aircraft or the control station.

Embodiments of the invention described herein thus provide systems and methods for arresting aircraft. In specific embodiments, the systems and methods can be useful in arresting light aircraft because they typically do not have the weight to penetrate available EMAS systems. The system is generally provided as a structure having a suspended layer of energy absorbing material. A lower portion of the system can have a lower strength, used as a method to suspend an upper, stronger/more highly energy absorbent portion of the system.
Embodiments of the present invention relate to composite materials for use as a vehicle arresting system (also referred to as an Engineered Material Arresting System (EMAS). Specific embodiments may use modified polymeric foams composites. The polymeric foams may include additives, coatings, combinations of both, or other features than render them useful for an EMAS. The polymeric foams may also have one or more modified surfaces that provide a protective crust. For example, the one or more surface may be modified by application of heat in order to help close the polymeric foam cells and/or to create an encapsulative surface. These features can provide enhanced weather resistance, fire resistance, moisture absorption, jet blast resistance, improve their energy absorbing properties, or other desired features.
