A heat exchanger assembly includes a core assembly having air passages that are closed off on at least one side by a closure bar. A reinforcing bar is received within a channel of the closure bar to create an interface with substantially no gaps that may accumulate moisture within the core assembly. The prevention of moisture accumulation at the interface between the reinforcing bar and the closure bar prevents potential damage caused by freezing.

The proposed UUAV provides a small, agile vehicle that leverages the unique principals of remote controlled model aviation. The UUAV also encompasses an aerodynamically shaped, gas filled wing that can be used to provide buoyancy for lift assistance both through the use of the lighter than air gas and by its aerodynamic shape in forward flight.

A heat exchanger uses a skeleton forming of a lattice of first and second bars to provide a box-like structure. Blocking bars are arranged between gaps in the first and second bars to provide a blocking surface to divert airflow around a portion of the heat exchanger core. A brazing material is used in the assembly of the core and the skeleton, which includes the blocking bars.

A plate fin heat exchanger is disclosed. The heat exchanger includes a plurality of plates defining a set of hot fluid passages between adjacent plates of the plurality of plates and a set of cold fluid passages between adjacent plates of the plurality of plates. A hot fluid inlet and outlet are located at a first face of the heat exchanger. A barrier is located between adjacent plates defining the hot fluid passages. The barrier extends between the adjacent plates and extends from the first face of the heat exchanger at a location between the hot fluid inlet and the hot fluid outlet in a direction perpendicular to the first face, and defines a first pass of hot fluid passages on a first side of the barrier and a second pass of hot fluid passages on a second side of the barrier.

A plate fin heat exchanger includes a plurality of finned cold layers configured to conduct a first fluid, and a plurality of finned warm layers configured to conduct a second fluid. The finned warm layers include an inlet side and an outlet side. A first portion of fins of at least one finned warm layer of the plurality of finned warm layers includes a plurality of aligned peaks and valleys defining a wave configuration for each fin of the first portion of fins. An upstream leading edge of the first portion of fins begins at a point of the wave configuration that is at least one of the peaks and valleys.

A method of extending the lifetime of brazed primary hot inlet wavy fin structures of aircraft heat exchangers includes inserting slots in the fins. The slots increase the mechanical compliance of the fins as well as act as crack arrestors should a thermally induced fracture occur. In an embodiment, the slots are inserted by EDM.

A heat exchanger includes a plurality of mini-channel tubes. The mini-channel tubes extends for an axial length defined between two manifolds. The mini-channel tubes include a plurality of generally rectangular flow passages. The generally rectangular flow passages are aligned adjacent to each other to define a lateral dimension. A first lateral width of the generally rectangular passages is defined with a ratio of the axial length to the first lateral width being between 201.3 and 215.3. An aircraft system is also disclosed.
