We have great relationship with the FAA and our JB10 has been granted experimental certification.

EDFs are really power hungry beasts! You have to use them for takeoff and then transition onto a wing ASAP or you’ll be out of juice at 250w.h/kg No loiter time possible. The issue with folding wings is that they can big stability issues. Probably not unsolvable but not simple.

Yes they are and it’s great but...it suffers the same limitations as any open rotor drone configuration, it’s really slow and really large

Fixed wing can glide, helicopters can autorotate, open rotor e-vtols don’t autorotate because they don’t have variable pitch blades and their inertia is way too low anyway. jet-vtols have no rotor blades at all so... you’re right if an e-vtol or jet-vtol experiences a catastrophic failure then it’s going straight down! Many of the e-vtol companies say they solve this by having x levels of redundancy..we don’t buy that at JPA. We want to build a saftey system that can rescue the pilot from 5 feet or 50 feet or 5000 feet. Now that’s a challenge! But we believe doable.

We use turbojets but are working on a 4:1 bypass ratio TF

We’re actively working with army, navy and marines in US. Why put a Blackhawk and crew at risk where one it a swarm of autonomous cargo Speeders can do same work. 400-600lbs cargo of equip, blood supplies etc. Not to be used for insertion of operators in covert mission but in overt ops our noise signature isn’t a factor.

Yes you are correct. We are also working on our turbofan. Way better sfc, quieter and cooler exhaust.

Every minute saved in reaching a stroke or heart attack victim reduces mortality by approx 10%. Worth fighting for?

If we can fly quickly AND safely and land within feet of an injured person and that makes a difference of them living or dying, isn’t that worth a shot?

We 100% agree and base level stablization is what we spend most of our engineering time on - both software and mech. We are learning a heck of a lot from our 1/3rd scale model

Depends on which aircraft but the JB11 is approx 110dba at 25ft

We are working also on micro turbo fans (<250lb thrust class). Current TBOs >250 hrs

The airflow works, we’ve modelled it. Pilot needs to wear similar jacket to current standard motorcycle jacket. No loose change in pockets

We were never part of the Martin JetPack project. Totally different tech.

Absolutely right

No we haven’t to 15k ft, we’ve modelled that. We’ve flown at approx 7k ft above mean sea level in alps

Our tech could not be more different to the MJP. Theirs was a gasoline engine powering a pair of ducted fans. Too many single points of failure and never able to keep the engine cool, not possible to fly much faster than 60mph. Ours is 1/3rd the size, will fly at 4x the speed. We’ve flown our jetpacks all over the world. We already have a development agreement with the US Navy. They are perfect for overt (perhaps not covert) military ops - insertion and extraction and getting medics into position. Why risk a Blackhawk and crew??!!

Why not for governments and EMS. If we can get EMS medics to heart attack and stroke victims just 1 min quicker the number of lives saved is 100,000 - 200,000/yr just in USA. Isn’t that worth taking a shot at?

I don’t understand the point about flying high enough. We can fly at over 15,000ft

The safety system has to be integral with initial design and it is. Before these are used in urban environments the machine must be able to set itself down safely regardless of the failure. That is possible.

Thank you, yes we really are but it’s cool to do. We should achieve up to 30mins endurance with exiting engines and if we move to a turbofan than 2-3 x that is possible

We probably have the highest wing loading of any aircraft, therefore the impact of turbulence is much less than fixed wing or helicopter. The pilot has belly strap and lock holding them to vehicle unless they need to release in an emergency in which case it has pyro cutter.

In rain you’d get wet just like riding a motorcycle on the road. The engines keep running fine.

Flying into birds is not recommended for any aircraft. They wouldn’t go into the engines but could hit the pilot then our safety systems would need to deploy.

Lightning usually won’t take an aircraft of any type out of the sky but may affect instruments.

Thank you!

The 1/3rd scale prototype is flying. In a number of ways what we’re doing is simpler than JA. We’re confident we can achieve our time goals.

We’ll count you in... in the future!

Hey maybe one day we can get it down to that kind of level

How do you do the economics on the value of the lives this can and will save?

Same way our jetpacks were accepted. Our stall speed is zero and with an engine out we can still control our flight path.

You bet. Thanks!

It’s not too different to riding a motorcycle. You can rest across the engine intake protection grills and not uncomfortable.
