Richard Mornington-Sandford – flight instructor and engineering trainer has a long history working with the Robinson brand. Before this episode if you told me that there was more than an hour conversation that you could get out of talking about the governor in Robinson type helicopters I would have been dubious. I was wrong! Today we have back on the show pilot and engineer Richard Mornington-Sanford. Richard Mornington-Sanford was an engineer in the RAF before branching out into the roles of a civilian flight instructor, licensed helicopter engineer and air accident investigator. A photo on his website has an endorsement from Frank Robinson in 1998 with at that point, 18 years of association with the Robinson Helicopter Company and its products. Richard is still conducting Robinson Pilot Flight Safety Courses around the world today. You can do the maths on the years of experience there. Richard was last on in episode 93 where he provides probably the best coverage of carburetor icing for helicopters that I’ve ever come across. There was a lot of good feedback in emails from that episode and I’m sure this one will be similar. We do chiefly talk about the Robinsons – R22 and R44 but there is plenty of generic governor operation content here that you can adapt to other types. If you are solely a turbine driver then I think this is good background info too and hopefully entertaining. Richard is living in rural Malaysia so the call connection was a little spotty in places but hopefully I’ve tidied it up ok. In this podcast we cover: Robinson R22 and R44 engine correlator Where the governor gets its signal inputs fromOperation of the governor and its inputs at different RPM rangesInter-action between turbulent conditions, the governor and carb icingGovernor-off training for pilotsFailure modes  Podcast: Subscribe in iTunes | Play in new window | Download Links from this week’s episode:Support the podcast on PatreonMornington Sanford Aviation – Richard runs a number of safety and engineering courses.

RWS 103 – Robinson Governor Operation with Richard Mornington-Sanford

Richard Mornington-Sandford – flight instructor and engineering trainer has a long history working with the Robinson brand. Most piston engine pilots will be at least passingly familiar with the theory behind the formation of carburettor icing. However most textbooks lean towards the operation of the carburettor in a fixed wing mounted engine. Helicopter engines, predominately the Robinson helicopter types but applicable to others as well, have their own unique challenges when it comes to carburettor icing and the use of ‘carb heat’ warm air.    Richard Mornington-Sanford was an engineer in the RAF before branching out into the roles of a civilian flight instructor, licensed helicopter engineer and air accident investigator. A photo on his website has an endorsement from Frank Robinson in 1998 with at that point, 18 years of association with the Robinson Helicopter Company and its products. Richard is still conducting Robinson Pilot Flight Safety Courses around the world today. You can do the maths on the years of experience there. From his website – “He is a Robinson Helicopters Accident/Technical Investigator and conducts the Robinson Factory Maintenance Course in the UK, Europe and Worldwide together with EASA Part 147 type training approval. With CAA engineering and flight instructor licences, he is credited with having unrivalled experience outside of the factory on the Robinson product.” Anyway, all that to say that the guy knows a bit about the innards of the Robinson product. I stumbled upon a 2012 PDF guide that Richard had written about carburettor icing only in the last few months. What stood out to me was that it was the first time that I had seen the topic of carb icing covered from a purely helicopter engine and helicopter operation view point. It was fascinating stuff and somewhat humbling that I hadn’t previously been exposed to some of the ideas the guide had in it. Fig 1 to the right is taken from Richard’s guide. You can download the full guide and see additional photos, drawings and graphs by clicking on the cover image immediately below. Very briefly – the carburettor is designed to deliver a fuel/air mixture to the engine pistons for combustion. If that air mass is sufficiently blocked by icing then combustion stops. Not a good thing. Even on a warm day the air moving through the carburettor can experience a significant temperature drop due to 1. the latent heat absorbed from the air as the fuel vaporises, and 2. the reduction in temperature and pressure as the air rushes through the venturi effect created by a less than full open butterfly valve. Now a big difference between the textbooks (which are fixed wing centric) and what happens in a Robinson R22 or R44 is that the books say that during takeoff there is very little chance of carb icing due to the high power setting and full open butterfly valve. However! In the R22 and R44 because of the de-rated engine, at sea level at takeoff power the butterfly valve is a long way from being fully open. How far? Look at Richard’s charts in the document below to find out.     Download Richard’s guide on carburetor icing in helicopters by clicking on the image above. In this podcast we cover: Causes of carbuettor icing and conditions that it is more likely to occurWhy helicopter engines are difference to fixed wing when it comes to icingThe history behind the Robinson R44 carb heat assist controlCorrect use of carb heat and why you must bring it on earlyMAP limits vs BHP limits and relevant safety noticesInsight into development of the takeoff power range limitation in helicopters    Richard conducting a Robinson Helicopter Company Safety course in Russia    Podcast: Subscribe in iTunes | Play in new window | Download Links from this week’s episode:Support the podcast on PatreonMornington Sanford Aviation – Richard runs a number of safety and engineering courses.
