Tilt-Rotors: Good but Sliced Bread is Still Better.


In the 1980’s the concept vehicle V-15 proved that tilt-rotor technology had matured to the point that maybe we could build a vehicle to overcome the speed and range shortfalls of the helicopter.  After much development, strong lobbying efforts by industry to overcome Congressional skepticism, and the normal growing pains of any new advanced technology, we have proved the V-22 Osprey brings a new dimension to the battlefield.
Operations worldwide have shown it to be more rugged than its critics foretold, and suitable for a wider range of missions than even its supporters imagined, but it is not the be all, end all of small cargo aircraft.  It is pretty expensive to operate and maintain, and it is not able to fit in even our largest cargo aircraft so getting to the remote areas where we go means it has to ride on a ship, or fly there itself.

Now the Army is looking to replace the ubiquitous UH-60 with a next generation of vertical-lift helicopters and Bell/Lockheed Martin’s entry is the V-280 Valor.  A new generation tilt-rotor that looks like the offspring of an Osprey and a Blackhawk. I would say if we had all the forward basing we had in the cold war this would be an almost ideal replacement, but we don’t.
So as the Army plans for its rapid deployments the long pole in its planning will the answer to the age-old question.  “How long will it take to get my stuff to the battle?”  It was the Union’s General Nathan Bedford Forrest who coined the axiom “Get there firstest, with the mostest” as his strategy.  That is sound advice, especially in today’s world where most US military is now garrisoned in the good old US of A. 
Today, we can cram at least two Blackhawks in a C-17 and I think four will go in a C­-5.  Traveling at Mach .8 (~450 kts) they will arrive significantly quicker than if the aircraft self-deploy at Mach .4 (~220 kts).  Even with tear down and build up the force will be ready to operate before the self-deploying assets are ready because you are not burning flight hours on either the aircraft or the crews.
The V-280’s competition is the Lockheed Martin-Sikorsky S-97 Raider.  Due to consolidation within the aerospace business we have a unique situation where one Lockheed Martin division is now competing against another Lockheed Martin division.  It is as if Lockheed Martin can’t lose.
