The RAT Pack

The RAT Pack provides Ram Air Turbines that generate power from flowing air. I was partly inspired by a documentary on the "Gimli Glider", a 767 that had to glide to a landing with nothing but batteries and a RAT to power critical systems. A couple of spaceplane landings where I had to constantly manage electric charge to maintain control and keep enough for the landing gave me some incentive to actually build it. The RATs are designed to provide emergency power and have peak power at or slightly above that of an RTG. Electric charge output is a function of both airspeed and atmospheric density.

RAT-1 "Pinwheel" Ram Air Turbine - As basic as they come, it provides little power and must be activated manually. RAT-360 "Cage Master" Ram Air Turbine - Generates more power and will automatically start up when electric charge is depleted. RAT-720 "Topper" Ram Air Turbine - A RAT built into a nosecone. It has a higher peak power than the RAT-360, but has a performance curve similar to the RAT-1. RAT-6000 "Pack Master" Ram Air Turbine - The most powerful RAT. This one has the ability to control electric charge flowing from its internal battery and turns it on only when it is activating. It is able to generate peak power over a broader range. EPM-MK3 "Emu" Emergency Power Unit - A complete emergency power solution with a RAT, Fuel Cell, and APU.

Thrust Reversers

Thrust Reversers redirect the engine thrust. They are used to reduce stopping distance once landed. I developed it primarily for Duna spaceplanes where a short stopping distance is a huge asset. They will redirect the thrust of the engine attached to them. Attaching multiple engines will not give you the desired behavior as only one engine will be reversed.

• TR-1 “Backup" Thrust Reverser - Designed to fit a Turbojet or RAPIER engine.
• TR-L “Way Back" Thrust Reverser - Designed to fit longer 1.5 m engines, particularly the LV-N.

Terrain Awareness and Warning Systems

A Terrain Awareness and Warning Systems (TAWS) gives you a chance to avoid a crash by warning you while you still have some time to react. It uses the radar altimeter and some calculations to figure out what the terrain looks like. It also has an obstacle detecting radar (FLT Radar), however it only activates below a certain altitude and uses a fair amount of power when in use.

• TAWS-1 "Lookout" Warning System - Equipped with Ground Proximity Warning System (GPWS) and Forward Looking Terrain (FLT) Radar.
• TRS-1 "Lookdown" Terrain Radar - Terrain scanning to improve landings.

Launch Escape System Trigger

I came across this post Launch Escape System Rocket Stack Failure Detection and thought it was in line with this mod and a great idea.

• LEST-1 "Oops" LES Trigger - Detects a unplanned dis-assembly and hits the abort button for you.
