The invention belongs to the technical field of helicopter tests, and discloses an engine compartment temperature field measuring device for a helicopter ground joint test, which comprises the following steps of: firstly, carrying out heat flow field theoretical calculation on a helicopter engine; three sections representing engine heat flow field distribution are selected from the front end to the rear end to be provided with a plurality of temperature sensor installation points respectively, temperature sensors are installed on the temperature sensor installation points respectively and connected with a temperature collection device, and after the temperature sensors send temperature signals to the temperature collection device, the temperature collection device sends the temperature signals to the engine. And the temperature acquisition device sends a temperature signal to the server. The temperature of the heat flow field is measured by using a contact type temperature measurement technology, the temperature field of the engine compartment of the helicopter-ground combined test bed is measured, the measurement principle is simple and practical, interference is not likely to happen, the maintenance cost is low, and temperature data can be displayed in real time; and a data basis is provided for the engine compartment heat flow field distribution condition and the function optimization of an engine compartment air inlet and exhaust system under various working conditions.
