Újabb cikk a H145M D2-D3/UH-72A -B összehasonlításáról .
"They were complimentary of the reliability, avionics, and general ease of use, with the only
consistent complaint being a lack of power in higher density altitude settings. "
- ez mg a D2, négylapátos rotorúról szól.
Ami természetesen földközeli magasságon, kánikulában is igaz.
D3/UH-72B modellről:
"Additionally, the fully automated FADEC starts are a vast improvement and markedly
less stressful than those in A model, which require manual modulation of the throttle, increasing the likelihood of a hot start. "
"Far more noteworthy is the inclusion of the
auto-hover modes, a valuable addition for hoist operations and even restricted visibility approaches. "
"
Does the five-bladed rotor system solve the problems with excessive vibrations in the four-bladed H145 D2? The short answer is, yes. It works as advertised, drastically reducing vibrations in both the front and back of the helicopter. For those not familiar,
the four-bladed H145 (BK117-D2) suffered from significant main rotor vibrations felt in the cabin. "
" In the event of spatial disorientation, a simple double tap of the cyclic “autopilot on” button will
automatically engage the autopilot and recover the aircraft to a level attitude. If in high or rising terrain, this can be coupled with a quick press of the
go-around button on the cyclic, putting the aircraft into a 1,000-foot (300-meter) per minute climb. "
"These features, coupled with
synthetic vision, add a level of comfort I find myself dearly missing when flying other military aircraft, particularly in marginal weather or on low illumination nights.
...
these capabilities should unquestionably be standard on all new military rotorcraft."
"With increased range and payload, as well as drastically improved ride quality and avionics,
there’s no objective metric, aside from speed, where the B-model isn’t an improvement over its predecessor. Based on conversations with those currently flying the A-model and my prior experience with the H145,
the new model will offer a significant jump in capability for nearly all current mission sets."
"
The UH-72B Lakota represents a drastic improvement over the UH-72 for Army aviators."
"While I’m still reticent about the
limitations of employing such solutions in combat and
the Lakota was clearly never designed for such environments..."
