Abstract
A landing gear assembly is provided. The landing gear assembly includes a shock strut. The shock strut includes a shock strut cylinder and a shock strut piston slidably disposed within the shock strut cylinder. The landing gear assembly further includes a temperature control unit assembly disposed within the shock strut cylinder. The temperature control unit assembly is configured to, responsive to a temperature within the shock strut cylinder falling below a predetermined temperature, circulate heated fluid into a chamber of the shock strut cylinder to heat gas within the shock strut cylinder.

A landing gear assembly, comprising:
- a shock strut comprising:
- a shock strut cylinder;
- and
- a shock strut piston slidably disposed within the shock strut cylinder;
- and
- a temperature control unit assembly disposed within the shock strut cylinder, wherein the temperature control unit assembly is configured to, responsive to a temperature within the shock strut cylinder falling below a predetermined temperature, circulate heated fluid into a chamber of the shock strut cylinder to heat gas within the shock strut cylinder.
An aircraft, comprising:
- a landing gear assembly, the landing gear assembly comprising:
- a shock strut comprising:
- a shock strut cylinder;
- and
- a shock strut piston slidably disposed within the shock strut cylinder;
- and
- a temperature control unit assembly disposed within the shock strut cylinder, wherein the temperature control unit assembly is configured to, responsive to a temperature within the shock strut cylinder falling below a predetermined temperature, circulate heated fluid into a chamber of the shock strut cylinder to heat gas within the shock strut cylinder.
A method of maintaining a compressibility factor of gas in a shock strut of a landing gear assembly of an aircraft, comprising:
- receiving, by a temperature regulator, a temperature sensed by a temperature sensor;
- and
- responsive to the temperature sensed by the temperature sensor being below a predetermined temperature, circulating, by the temperature regulator, heated fluid from a heated fluid chamber into a heat exchanger within a chamber of a shock strut cylinder to heat gas within the shock strut cylinder.
