Hi Matt,
Will check but I currently have two types of plugs and they can have keying inserts installed. Haven't done that yet but would be a good idea.
By the way, booster is not a vehicle booster rather a pressurant booster ie to pump from say 200 to 350 bar.
The telemetry is not encrypted but I feel the risk to me having an unwanted packet coming in is very very low.
Firstly the radio configuration is custom ie pre-amble length, air bit rate, modulation width etc are likely unique.
Secondly the transmit and receive headers (which act as filters) are also non-default so if someone else somehow had the same radio config and the same channel, they would also need to have the same 4 byte header to make it through the radio packet engine filter.....let alone getting a packet protocol that would match one of mine ie if the packet type does not match one of a std list I have defined, the packet is rejected also.
No specific liquid fuel plans at this stage, other than to include the valving and channels to support it. Once you go down the path of supporting pressurants etc, adding these bits for a liquid fuel is not such a big deal. The pressurant capability was added to support approaches such as chilled N2O + Dissolved O2 (Nytrox) in which case the O2 would be considered the pressurant (albeit only at 69bar).
I think a good improvement to this arrangement would be to move the Ox and Fuel valves + actuators to a separate plate that can be mounted right near the vehicle. That way I can eliminate the risk of an Ox &/or fuel leak into the GSE control box
Is this a horizontal test rig? If it’s vertical then you have to worry about the trust pushing the rig over with a diverter.
