Short description of requirement:
Breathing apparatus. Royal Air Force Centre of Aviation Medicine (RAF CAM) require the capability to train multiple aircrew in the use of pressurised breathing apparatus, as used on aircraft, and also require the functionality for on-man testing of the G-suit apparatus which the Survival Equipment Section (SES) supply to the aircrew before the aircrew undergo High-G training on the High-G Training & Test Facility at RAF Cranwell.
The Authority is requesting information on two topics:
• Market innovative solution in combining all or some of the ‘Single-Point Pressure Breathing Rig’, ‘Multi-Point Pressure Breathing Rig’, and ‘Scenario Based Hypoxia Trainer’ capabilities.
• Market alternative solutions to the current individual capabilities.

10/03/2021 12:00 Information Requested: Please note that this is a Request For Information (RFI) only. This request is not a commitment by the Authority to launch a formal procurement process and the requirement, described below, is subject to change. The objective of this RFI is to explore alternative solutions to the current capabilities.
Information shared at RFI may be shared at an Invitation to Tender (ITT) or Invitation to Negotiate (ITN) stage of procurement, if an ITT or ITN is pursued by the Authority. Information may be shared in relation to how the Requirement was prepared and developed. However, information, resulting from any RFI, marked 'Commercially Sensitive' by the respondent, will not be shared outside of the Authority. The Authority shall reserve the right to reject submissions marked as 'Commercially Sensitive'.
Multi-Point Pressure Breathing Rig (MPPBR):
Used to train multiple (up to 8) aircrew in the use of pressurised breathing apparatus (supplied by SES), as used on aircraft. It is a large, custom made, wooden rig, with 8 student seats and an instructor’s console. It requires a pressurised air supply, which is currently supplied by hardwired pipes running from a separate air compressor and reservoir which are in an external plant room. This is controlled through a regulator and gauges which are wall mounted adjacent to the MPPBR. The MPPBR is used several times a month, depending on the courses that are run at RAF CAM.
Single-Point Pressure Breathing Rig (SPPBR):
Used to train individual aircrew in the use of pressurised breathing apparatus (supplied by SES), as used on aircraft, particularly fast jets (Typhoon). It is also used for a functional on-man test of the G-suit apparatus which the survival equipment fitters supply to the aircrew, before the aircrew undergo High-G training at RAF Cranwell. It consists of a desktop console, which is connected to a high-pressure breathing air cylinder. It also has a custom-made seat rig, which replicates an aircraft seat, with a harness/strap system and connections for the seat and mask to be connected. The seat can also be dropped back horizontally to assist medics in the event of a student becoming unconscious. The SPPBR is used monthly, occasionally fortnightly, depending on course requirements.
Scenario Based Hypoxia Training (SBHT):
Used to demonstrate the effects of hypoxia on individuals, by administering breathing air with a reduced oxygen content with the assistance of a doctor and a medic. This is done using a Reduced Oxygen Breathing Device (ROBD) which mixes breathing air with nitrogen at a predetermined rate. The individual’s heart rate and oxygen saturation are monitored throughout, by use of a pulse oximeter. Once an individual has experienced enough hypoxia symptoms, the ROBD administers 100% oxygen to allow the individual to recover. This system is used as an inherently safer alternative to carrying out hypoxia training within a hypobaric chamber. The SBHT facility is used several times a week, however depending on course requirements it can be used daily.
Multi-Point Pressure Breathing:
The equipment shall be able to expose eligible personnel to normobaric pressure breathing techniques:
• Conduct collective training for 8 personnel, with an objective aim of 12 personnel.
• Conduct training for pressure breathing up to 30mmHg.
• Use as aircraft breathing systems.
Single-Point Pressure Breathing:
The equipment shall be able to assess the integrity of oro-nasal oxygen mask seal and pressure garments in a human subject breathing at increased airway pressure, in the laboratory:
• Conduct pressure breathing with pressure demand regulator to support breathing.
• Deliver breathing air in the range 0-110mmHg.
• Monitor leakage from mask/garments using inbuilt leakage indicator.
• Inflate chest counter-pressure garment and anti-G garments simultaneously to same pressure as breathing pressure.
• Seat and harness with ability to recline in case of loss of consciousness.
• Gases supplied through representative aircraft fittings.
• Peak inflation (including all garments) within 1 second.
Scenario Based Hypoxia:
Capability to demonstrate:
• Oxygen levels representative of atmospheric gaseous mix at 25000ft.
• Rapid onset of reduced oxygen levels within 1-2secs.
• Slow onset of reduced oxygen over several seconds to minutes.
• Provide emergency oxygen supply in the event of an emergency.
Capability to train:
• Concurrently train 3 students each under the supervision of a medic and a medical professional.
• Training serial to last 10 minutes
• Deliver training to a course of 15 personnel within 75mins
Based on the information above, there are key questions the Authority would like information and feedback on:
Is there any piece of equipment on the market or one that could be made bespoke, that encapsulates all three of the above capabilities and delivers the requirements outlined? If not, is there any proposed innovation for delivering the above requirements?
As the equipment captures 3 capabilities, would there be a single point of failure or the ability to isolate individual ‘stations’ if there was a maintenance problem so as not to cease all outputs?
Dependent on the proposed solution, would this be able to deliver the different capabilities all at the same time? If not, would this be possible?
What would be the ROM dimensions of this equipment in its total (noting the requirement to separate out gas cannisters and piping)?
What would be a ROM cost of the proposed piece(s) of equipment versus a ROM cost of delivering all 3 capabilities as separate equipment?
-Any clarifications or responses should be sent via email to
. Responses should be limited to 4 pages of A4 in pt11 Arial font, and be sent by 1200hrs on 10th March 2021.
