Design Your Own Helicopter

Recommended Posts

I just thought it would be fun for people to come out with what they think would be the ideal helicopter for the job they usually do.

DeHavilland actually conducted such a survey before they designed the Beaver.

It doesn't have to be fully detailed.

Technology within the bounds of reality ( No warp speed or cloaking devices!)

 

Anyhoo I will start with the Bung Vertileap 2005 Offshore Mk1:

160 KT Cruise @ Best range speed@ max Gross.

185 KT VNE

 

200 NM Operational Radius with IFR Reserves.

700 NM with IFR reserves Ferry range without extra tanks - but provision for them.

 

15 Pax and lots of Baggage space ( 250 LBS per pax+Bags ) @ 200 NM mission range

 

Twin engines - placed so that access to both sides of each engine is possible.

 

OEI Hover and flyaway at Max gross at 1000 ft @ 35 Deg C. 0 wind ( without having to replace the other engine afterwards Thank you very much )

 

FADEC or DECU or whatever you wanna call it.

 

Throttles on the collective - because that is where they should be!

 

No Boost pumps

 

No AC power

 

High and Low Pressure refueling.

 

No center column or consul in the cockpit. free Access to the pax area.

 

Glass cockpit dual GPS. Radar, TCAS , Satphone and flight following - all the bells and whistles.

4 axis outo pilot with Auto hover.

 

 

Comfortable fully adjustable pilot seats.

 

Good Visibility of helideck from the cockpit.

 

Easy access doors to the cockpit ( sliding would be good )

 

Hoist provisions.

 

2 stretcher capability without any seat removal.

 

Sliding doors for the pax compartment - Fully jettisonable

External liferafts.

 

Sliding doors for the Baggage compartment - can be opened from either side while pax doors open.

 

Rotor system and tail rotor with at least 7.5 foot clearance on the ground at idle at Max gross.

 

And MOST IMPORTANT - Airconditioned Big time!!!!!!

Adapting the original post to what I do:

 

 

160 KT Cruise - 185 KT VNE

 

2.8 hours endurance

 

2 crew and 0 Pax with 400lbs of Baggage capacity

 

Tandem seating (No center column or consul in the cockpit)

 

Twin engines - placed so that access to both sides of each engine is possible.

 

OEI Hover and flyaway at Max gross at 4000 ft @ 30 Deg C. 0 wind ( without having to replace the other engine afterwards Thank you very much )

 

Max gross external 18000 lbs Empty weight 6500 lbs

 

FADEC or DECU or whatever you wanna call it.

 

Fuel burn 650 lbs/hr

 

Throttles on the collective - because that is where they should be!

 

No Boost pumps

 

Customer AC power and hydraulic power

 

High and Low Pressure refueling.

 

Glass cockpit dual GPS. TCAS , Satphone and flight following - all the bells and whistles.

 

Comfortable fully adjustable pilot seats.

 

Longlining visibility similar to Kmax

 

Easy access doors to the cockpit ( sliding would be good )

 

And MOST IMPORTANT - Airconditioned Big time!!!!!!

 

 

These specs are based on a study done using a Bell 214 ST drivetrain and rotor system with a completely redesigned fuselage. The empty weight of 6500 lbs would most likely gain a thousand pounds after the engineers add on the hydraulic pack and such. The origins of the study was to convert a Bell 214B to a twin engine with the engines and bigger rotor system of the ST. It was to be called the Super Bee! Northern Mountain got wind of this rumour and fell for it hook, line and sinker. One of the owners made a special trip to Chilliwack demanding to know what was going on.

Hi Sharkbait,

 

You pretty well decribed a Super Puma. It doesn't quite get the speed you wanted but we have used it to fly 200 miles offshore in several places and once did a 756nm ferry flight and still had 1500# of fuel when we landed.

 

15 Pax is no problem,

 

The engine access is great,

 

The performance is close (I didn't get my manuals out but I seem to remember that we were Cat A at MGTOW with a 10 knot headwind at 15C,

 

I'm sure that the latest versions have all the bells and whistles you wanted,

 

You have to see the North Sea pilot's seats to believe them, adjustable, thigh support, sheep skin, etc.,

 

Visiblity, access, hoisting, stretchers, all good.

 

All you need to do is get the **** rotor to turn in the right direction.

The fishing is great, as usual, got interupted by a trip to Hurricane land for some Simulating but that's all over now and back into the river for me. Just imagine, sunny skies, gurgling river, Eagles squawking in the trees behind you, dead salmon all over the shore line stinking to high heaven, NIRVANA!!!!!

 

Unfortunately it will all be over too soon and I'll be seeing you in Du' on the 2nd.

 

P.S. That feet on the floor thing is called "Teaching the Tiger to roll over and play dead".

Reddawg:

Oh Great now we'll both go to ****!!

I trust stimulation was a pleasant experience as usual.

I hope you are going to smoke some of that salmon.

I will be there - perhaps in time for Brekkies! Bacon! Pancakes! I am drooling already.

The Deuce and I gave up cancer sticks - cold turkey - haven't killed anybody yet.

Still hot and humid but should start to cool for your arrival. I wouldn't pack the longjohns however.

See you soon.
