Gas driven gyroscope with extended rundown time |
摘要 |
A gas gyroscope 11 is provided with an aspirator pump 71 in order to evacuate gas from the main chamber 19 of the gyroscope 11. The evacuation of gas reduces windage and other air friction encountered by the gyroscope's rotor 21 and thereby extends the rundown time of the gyroscope. The aspirator 71 may be energized by a dedicated compressed gas source such as a compressed gas chamber 91. Alternatively, the aspirator 71 may be provided with ram air or bleed perpellant gases.
