GAC’s Technology

What is GAC Solving?

GAC is working to solve the autonomous delivery of freight. For an electric drone to carry 15lbs of cargo, it requires several innovations:

1

First, the aircraft structure needs to essentially be a flying battery, in the same fashion Tesla envisioned the electric car

Vayu Aerospace holds the patent for this flying battery concept.

2

Second, the ability to store more energy per kg would need to be greater than traditional lithium-ion batteries can deliver.

Elecjet SSBs provide more power and energy density than Lith-ion batteries.

3

Finally, the aircraft must be capable of quickly replenishing its electrical charge to keep aircraft in continuous rotation.

Elecjet SSBs offer rapid and safe charging.

GAC’s Workhorse Drone for Package Delivery

Vayu's US-2 features best-in-class technological proficiency expected from a high-end, high performance drone.

This unmanned aircraft is capable of doing multi-hop deliveries, in addition to situational awareness through aerial recon.

*The US-2 is currently under development and in its testing phase. The US-2 shown is the current engineering prototype

The US-2 airframe will be modular and made of solid-state batteries making it essentially a flying battery.

The US-2 is capable of carrying >15lbs (>7kg) for 15 miles (>24km) or 40 minutes of continuous flight at full weight capacity. With a lighter payload, the US-2 offers up to 3 hours of flight time.

Vayu’s G-1 VTOL Aircraft

GAC’s Long Distance Drone

The Vayu G-1 platform is an unmanned autonomous VTOL (vertical take-off and on landing) aircraft built to support a wide range of solutions including package and medicine delivery, in addition to aerial surveillance/recon depending upon the application.

The G-1 is configured with eight electric motors for takeoff / landing - and a gasoline engine for forward fixed wing flight. Inflight transition between the electric and gasoline engine is seamless The gasoline engine charges the batteries while in flight.

Solid State Batteries

What is a Solid State Battery?

Solid state is a very broad term for the reduction or elimination of all liquid or semi-liquid materials in a battery and results in a completely solid battery.

Current batteries have liquid electrolytes that are usually some sort of gel. Solid state technology, replaces the liquid electrolyte with a solid sheet-like material such as ceramic oxide. The reduction in size of liquid electrolyte to solid electrolyte is dramatic.

Since the liquid electrolyte originally contributed to a very large amount of a battery’s volume, this means the battery, as a whole, sees a very dramatic size reduction. This is why solid-state batteries see improvements of energy density ranging from 30% to 100%.

Solid State Battery Cell Technology

Increasing both energy and power density along with safety as compared to traditional Lithium-ion battery cells.

Elecjet’s AX Class of Batteries are ultra-safe version and can withstand a variety of survivability use cases.

Battery Innovation Center (BIC) Testing

“I am extremely impressed with the performance of this battery cell relative to other cells that we have tested at BIC. Somehow, its energy density exceeds some of the best NMC technologies that BIC has tested while being solid state and maintaining comparable C-Rate performance.

From an EHS testing perspective, it has been shown to maintain stability under some amazing abusive conditions in contrast to the fielded lithium-ion chemistries that we see today. I am excited to continue testing and characterizing the abusive/performance specifications and see if we can find where the engineering tradeoff will be, assuming it exists.” -Danny Marshall Lead Testing and Evaluation Team Engineer

Solid-State Battery Features & Benefits

Energy Density

The energy density of batteries of similar electrical performance is increased from 30% to 100%, depending on application.

Power Density

Energy density is improved while C rates are improved. This leads to an incredibly enhanced power density that is several folds better.

Longer Life Cycles

Capabilities of charging at 4C and discharging at 7C rates for over 2400 life cycles in as little as 15 minutes

Thermal Safety

SSBs operate in a wider range of temperatures than traditional batteries, surviving thermal runaway up to 428°F, traditional lithium batteries can experience thermal runaway at around 266°F
