An intelligence, surveillance, and reconnaissance system is disclosed including a ground station and one or more aerial vehicles. The aerial vehicles are autonomous systems capable of communicating intelligence data to the ground station and be used as part of a missile delivery package. A plurality of aerial vehicles can be configured to cast a wide net of reconnaissance over a large area on the ground including smaller overlapping reconnaissance areas provided by each of the plurality of the aerial vehicles.

Modular flying platform including an airship body defining an internal space and configured to achieve buoyancy, an internal structure supporting a transfer channel, an attachment mechanism positioned on the transfer channel to detachably connect with a second platform. The transfer channel is configured to permit transfer therethrough of a payload between the flying platforms when securely connected. A chain of modular flying platforms with one or more motors mounted to the airship body to control motion thereof. A method for managing a chain of modular flying platforms includes deploying a plurality of platforms, connecting the platforms to form the chain, transferring a payload through channels of the connected platforms and distributing at least one of propulsion, electrical power and computing across the chain.

A hydrogen boiloff capture system. The hydrogen boiloff capture system having a cryogenic tank for storing liquid hydrogen. The hydrogen boiloff capture system also includes an intermediate tank fluidically coupled with the cryogenic tank. The intermediate tank is configured to receive hydrogen gas boiloff from the cryogenic tank. The intermediate tank is further configured to provide the hydrogen gas boiloff to a lighter-than-air craft to regulate buoyancy of the lighter-than-air craft. The intermediate tank is also configured to provide the hydrogen gas boiloff to a hydrogen fuel cell coupled to the lighter-than-air craft.

The disclosure herein provides an alignment and safety device for the cowls of the nacelle of an aircraft engine formed by first and second parts to be arranged opposite of each other at the lower edges of the cowls that include first and second alignment arms configured with a portion arranged to enter inside the inner space of the nacelle covered by the opposite cowl. One of the parts includes a blocking member configured to be interposed between the cowls after being unlatched to facilitate their opening operation and also when they return to the closed position from an open position if they are misaligned to facilitate its alignment and subsequent latching applying a force F on the blocking member.

An antivibration suspension system of an aircraft, the antivibration suspension system comprising a lever and an oscillating mass. The antivibration suspension system comprises a mechanical motion amplifier device interposed between the lever and the oscillating mass, the motion amplifier device being provided both with a mechanical inlet constrained to move in rotation with the lever about a control axis and with a mechanical outlet driving rotary movement of the oscillating mass.
