External vs. Internal Ballast Systems
Created by Aeros’ Aeroscraft Division, the Aeroscraft is a Rigid Variable Buoyancy Air Vehicle that is designed to control lift in all stages of air or ground operations, including the ability to offload cargo without re-ballasting. Unlike Airships and Hybrid Airships, the Aeroscraft is different.
The Past
Airships and Hybrid Airships have effectively provided a broad range of services, including advertising, surveillance, broadcasting and communication missions. However, they have considerable limitations in transporting cargo. The main operational challenge that Airships and Hybrid Airships face is the inability to control static lift while cargo is offloaded. The static lift that comes from helium gas is responsible for lifting tens of tons of cargo. But once the cargo is off-loaded, Airships and Hybrid Airships become extremely light, and the static lift causes them to float away. During this process, they require ballast (dirt or water) exchange to keep them anchored to the ground. Using ballast not only is a disadvantage if these resources are not available, but is impractical to manage. This is the main reason why Airships and Hybrid Airships have never been successfully used for cargo transportation. Moreover, they have a non-rigid structure that is not only more prone to puncture, but less dense compared to a rigid structured vehicle.
The Solution
The Aeroscraft answers all vital needs that are lacking in today’s current transportation industry - needs that are not addressed by other existing transport vehicles. The Aeroscraft is the only Rigid Variable Buoyancy Air Vehicle of its kind. What makes the Aeroscraft unique is that it has an Internal Ballast Control system, which allows it to offload cargo, without using ballast. Built with a rigid structure, the Aeroscraft can control lift at all stages with its Vertical Takeoff and Landing (VTOL) capabilities and carry maximum payload while in hover. These capabilities make the Aeroscraft more advanced compared to Airships and Hybrid Airships. The Aeroscraft also needs no hangar facility or airport, nor any excessive maintenance - making it the pinnacle solution for transport services.

- Unable to control static lift, and requires ballast to stay anchored after cargo has been off loaded
- Leaves environmental footprint by disrupting natural resources by re-ballasting
- Needs Runway to takeoff & land
- Non-Rigid Structure

- Does not require ballast because the system has its own `Internal Ballast Control` system
- Vertical Takeoff & Landing (VTOL) and hover, at max payload
- Rigid Structure
Airships & Hybrid Airships

- Location of Payload: External to envelope
- Payload (Weight and Volume): Common
- Durability: Punctures in envelope cause immediate pressure and integrity loss and require early repair
- Design: Punctures in envelope cause immediate pressure and integrity loss
- Time To Produce: Component fabrication and integration must be done in series
- Integration: Contingent on gondola design
The Aeroscraft

- Location of Payload: Internal to envelope
- Payload (Weight and Volume): Common
- Durability: Very low internal pressure - punctures (holes) do not jeopardize structure integrity
- Design: Reliable structure
- Time To Produce: Components are fabricated in parallel, and quickly integrated at once
- Integration: Ease of structural integration (e.g., hard points)
