1. A gas turbine engine mounting assembly connecting a gas turbine engine to a pylon, the engine comprising:
- a fan casing; and
aa core casing, the mounting assembly comprising;
a front beam mount connecting the fan casing to the pylon, the front beam mount carrying vertical load, side load and torque during operation of the engine; and
a plurality of carrying arrangements carrying thrust, lateral and vertical loads during operation of the engine, each carrying arrangement comprising a rear load absorbing assembly connected to the core casing, the rear load absorbing assembly absorbs thrust, lateral and vertical loads during operation of the engine and defines a rear mounting point, and each carrying arrangement further comprising first and second forwardly extending stabilizing struts which extend between the rear mounting point and two forward mounting points on the fan casing, said plurality of carrying arrangements being arranged adjacent each other and circumferentially surrounding said engine, each stabilizing strut of each carrying arrangement is coupled to a stabilizing strut of an adjacent carrying arrangement at each forward mounting point, wherein the rear mounting points are configured to attach to the pylon and the pylon connects to only one of the rear mounting points so that thrust is transferred from the core to the pylon through the rear mounting point via the stabilizing struts during operation of the engine.

Abstract
An engine mounting assembly for an engine, e.g. a gas turbine engine comprises a plurality of carrying arrangements. Each carrying arrangement comprises a rear load absorbing assembly. Each load absorbing assembly provides a rear mounting point for an engine carrier. Each carrying arrangement further comprises first and second stabilising members extending forwardly from the rear mounting point of the rear load absorbing assembly to first and second spaced forward mounting points for an engine carrier.
