Running exclusively off jet power would require an extremely (impossibly?) strong compressor stage coupled a powerful APU to generate lift. It's definitely not light enough to take off without tiltrotors.

The concept is the compressed air sent through slits in a thruster, creating negative pressure that draws in surrounding air, resulting in increased thrust, there’s a concept already of this, check the above reply.
From that link, "the system delivers 10% more thrust [...] than a small turbojet."
They are still very deeply limited by compressor technology, regardless of whether they use combustion or electric propulsion.
