KiloNewton/Pound foot of thrust into Horsepower units

If you need an airplane with VTOL capability then the Osprey might be one to consider, but you will pay dearly for that capability.

My understanding is a photon will warp spacetime because of its momentum.

You mean by high fuel consumption due to VTOL?

 

[David Lewis]

Poor fuel efficiency is only the tip of the iceberg.

What else?

 

[David Lewis]

Mechanical complexity, low reliability, astronomical acquisition & operating cost, maintenance requirements, accident rate and pilot skill required.

Yet all these factors can be sorted out in the design upgrades of later class of VOTLs/STOLs. I believe Osprey's current design is good enough to inspire a whole new class of aircrafts without competing with conventional helicopters or fixed wing planes. A lot of its maintenance and handling complexities if any are I believe due to its unique use of twin turbo shafts which perhaps in future designs would become more integrated with the wing and fuselage, making the aircraft easier to operate.

 

[David Lewis]

You're right. As technology advances, VTOL will become more competitive with conventional fixed wing.

I believe VTOLs will add to the vital side of aviation nomenclature of near future, let's say within a decade or so if I am not over stating. The reliability, frugality, handling parameters, usability and overall performance criteria of conventional fixed wing planes I don't think can be competed with in the traditional operational domains, at least not in foreseeable future.

My understanding is a photon will warp spacetime because of its momentum.

Relativity equation states that energy of a particle is product of its mass and square of its velocity at the speed of light. At this state the particle mass simply converts to energy aligned to universal law of conservation of energy. To go beyond spacetime threshold a force has to be acting on the photon by virtue of its change in momentum or simply it needs to accelerate, p=mv or f=m(v2-v1) which is not possible in our dimension so thankfully spacetime would stay intact. Am i right?

No. It does not.

Check out this container ship, apparently the largest of its kind in the world. The installed engine powerplant capacity of this class of diesel piston engines is upward of 69000 KW or 93000 hp.
