Concerning the VHA main and tail rotor blades on the BH206LR.
I’ve had the pleasure of putting the new VHA main and tail rotor blades through its paces since Aug/19 through to mid Oct/19. The roughly 200 hours have been a combination of point to point flights, gross load flight from departures to landing with as heavy a load with in its gross weight parameter, I’ve long lined, I’ve done a combination of forward, rearward and side ward flights, I’ve auto’d.
Both heavy internal and external combinations have only indicated one thing. These blades both main and tail rotor, has brought the Longranger to the standard that the Bell manual preaches. The Bell OEM blades have been particularly sub standard by comparison. The difference is like apples and oranges.
There doesn’t appear the necessity to even write about the Bell OEM blades because everyone knows of them.
From the start, the asymmetry of the [VHA] M/R, its rigidity, and the curved smooth tips have provided superior, lifting, speed and controllability. The L/R is now a different aircraft.
The single change, I as a pilot have had to do, is change my habits to provide room to let the VHA blades work to their potential. It appears to provide excelled performance as a result of slowing down my input feeds. It took a few attempts, but the results showed themselves time after time.
I’ll go on about the VHA main rotor blades again, but as for now let me be the first to say, take a chance as an operator or pilot. These blades are what Bell had been looking for in the first place. VHA has more than achieved that end.
The tail rotor blades have excelled in this regard as well. No longer am I living on hard left pedal anymore. As most can attest, whether the aircraft is flown with or without weight, the left pedal to the floormat, is never far enough to the floor. The VHA tail rotor pedals are now for me, stable and neutral. At no time in the last 3 months have I adjusted for any combination of flight to hard left pedal. If I did I would be still revolving in circles. Who da’ thought.
Three areas have made the LR a better aircraft. Since Rolls Royce decided to pick up the parts that Allison decided to discard, the engine no longer leaks oil. That in itself is novel. There are so many more positive attributes RR has brought to the table to provide a breath of fresh air to the 250-C20 series. It was so tired for such a long time. It’s back!
In addition to RR stepping up the game, so has VHA. Between the Main and Tail Rotor Blade improvements on the LR, it has simply become a better aircraft. Lift, speed, controlability, comfort and reliability have now been put to the front of the class. Personally I always thought Allison was the ugly twin sister to Ariel. Not any more!
