A turboshaft engine is a form of gas turbine that is optimized to produce shaft horsepower rather than jet thrust . In concept, turboshaft engines are very similar to turbojets , with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops , with only minor differences, and a single engine is often sold in both forms.

In most designs, the gas generator and power section are mechanically separate so they can each rotate at different speeds appropriate for the conditions, referred to as a ' free power turbine '. A free power turbine can be an extremely useful design feature for vehicles, as it allows the design to forgo the weight and cost of complex multiple-ratio transmissions and clutches . An unusual example of

2835-584: The largest SAR to date. Ground search and rescue is the search for persons who are lost or in distress on land or inland waterways. People may go missing for a variety of reasons. Some may disappear voluntarily, due to issues like domestic abuse . Others disappear for involuntary reasons such as mental illness, getting lost, an accident, death in a location where they cannot be found or, less commonly, due to abduction . Ground search and rescue missions that occur in urban areas should not be confused with "urban search and rescue", which in many jurisdictions refers to

2898-691: The location and extraction of people from collapsed buildings or other entrapments. In some countries, the police are the primary agency for carrying out searches for a missing person on land. Some places have voluntary search and rescue teams that can be called out to assist these searches. Search and rescue agencies may contain small specialist teams for executing operations where there are specific environmental risks. Examples include swift water rescue, flood response, technical rope rescue, confined space rescue, over-snow rescue, and thin ice rescue. Mountain rescue relates to search and rescue operations specifically in rugged and mountainous terrain. Cave rescue
