15 System Testing and Validation Technology of Lunar Lander
Fig. 15.16 Test for 7500 N engine thrust pulsation effect on GNC sensors of the Chang’E-3 lunar
lander
15.8 Joint Firing Test of Throttling Engine and GNC CCU
15.8.1 Test Objective
The objective of joint firing test of throttling engine and GNC CCU was to verify the
control coordination and compatibility of CCU with throttling engine, and measure
the average specific impulse during frequent thrust throttling in the approaching and
hovering.
