A supply drop assembly for delivering one or more payloads via an aerial vehicle, the assembly comprising a payload body configured to receive a payload; and one or more wings attached to the payload with a connector or integral to the one or more wings; wherein when the supply drop assembly is dropped from the aerial vehicle, the one or more wings start rotating thereby generating lift and slowing the rate of descent of the payload as it falls downwards to a recipient.

System and method for low velocity aerial supply drop

A combustion system such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).

Fuel combustion system with a perforated reaction holder

Systems and method for active control of stationary vortices for aerodynamic structures are disclosed herein. In one embodiment, a method for active control of vortices over a solid surface includes: generating vortices proximate to the solid surface; sensing locations of vortices by printed skin sensors; and maintaining the vortices in their fixed spanwise positions with respect to the solid surface by actuation of printed skin actuators.

Active control of vortices for skin friction reduction

A burner includes a porous flame holder configured to support a combustion reaction to achieve a very low output of oxides of nitrogen (NOx).

Porous flame holder for low NOx combustion

Pre-mixed fuel burner with perforated flame holder

A perforated flame holder and burner including a perforated flame holder provides reduced oxides of nitrogen (NOx) during operation. The perforated flame holder includes a pattern of elongated apertures extending between a proximal and a distal surface of the flame holder relative to a fuel nozzle. The perforated flame holder can provide a significantly reduced flame height while maintaining heat output from the burner.

Burner including a perforated flame holder spaced away from a fuel nozzle

A combustion system includes a perforated reaction holder having perforations defined to compensate for a non-uniform velocity of fuel and/or oxidant received across an input face of the perforated reaction holder.

Duplex burner with velocity-compensated mesh and thickness

A fire tube boiler includes a perforated flame holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).

Method for low NOx fire tube boiler

A combustion system includes an electrically actuated flame location control mechanism.

Combustion system with flame location actuation

A combustor may include a nonmetallic combustor body configured to hold a combustion reaction. The combustor may include and one or more electrodes disposed outside the nonmetallic combustor body and configured to apply electrical energy to the combustion reaction. The combustor may include a power supply operatively coupled to the one or more electrodes.

Combustor having a nonmetallic body with external electrodes

According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.

Method for combustion of multiple fuels

In a combustion system, a charge source is configured to cooperate with a collection plate and a director conduit to cause at least one particle charge-to-mass classification to be reintroduced to a flame for further reaction.

System for electrically-driven classification of combustion particles

An inertial electrode launcher may be configured to project charged particles or a voltage comprising an inertial electrode proximate a flame or combustion gas produced by the flame.
