#367 Blimps for the Rich

#367 What might a blimp big enough for 10 people and 2000 square feet cost?

The cost of a blimp that can hold 10 people and has 2000 square feet of space would likely be in the millions of dollars. The price would depend on several factors, including the materials used to construct the blimp, the technology and equipment installed, and the level of customization and luxury desired. Additionally, operating and maintaining a blimp of this size would also be quite expensive. It is difficult to give an accurate price without more information about the specific design and features.

How might it compare to a yacht of the same size?

A yacht of similar size to a blimp that can hold 10 people and has 2000 square feet of space would likely be much more expensive. Yachts are typically made from high-end materials such as fiberglass, carbon fiber, or wood, and are often equipped with luxury amenities such as multiple bedrooms, bathrooms, kitchens, and dining areas, as well as a variety of recreational and entertainment equipment. They also have more specialized features such as air conditioning, generators, and water making systems.

Additionally, yachts typically have engines, propulsion systems and navigation equipment, which are more expensive than the propulsion systems of blimps.

Yachts are also much more complex to build and maintain, and they require a crew to operate, which increases the overall cost.

It's safe to say that a yacht would be several times more expensive than a blimp of the same size.

Keep in mind that these are rough estimates and the final cost would depend on the specific design and features of each vessel.

List all components, down to the smallest, of the described blimp

There are many components that make up a blimp, including:

1. Envelope: The envelope is the large, balloon-like structure that contains the helium or other lifting gas. It is typically made from a strong, lightweight material such as polyester or nylon.
2. Helium or lifting gas: This is the gas that provides lift to the blimp. Helium is the most common lifting gas used in blimps, but hydrogen or hot air can also be used.
3. Gondola or cabin: This is the passenger compartment of the blimp, where passengers sit or stand during flight. It is typically located below the envelope and is suspended by cables.
4. Propulsion system: This is the system that propels the blimp forward. This can be either an engine and propeller or an electric motor with a fan.
5. Control surfaces: These are the surfaces that allow the pilot to control the blimp's direction and altitude. They include fins, rudders, and elevators.
6. Ballast tanks: These are tanks that hold ballast, which is a material that can be dropped to control the blimp's altitude.
7. Fuel tanks: These hold the fuel for the blimp's engines or electric motor.
8. Lights: The blimp will have navigation lights, anti-collision lights, and landing lights.
9. Electrical system: This system provides power for the blimp's lights, control surfaces, and other equipment.
10. Communication and navigation systems: These systems include radios, GPS, and other equipment that allow the pilot to communicate with air traffic control and navigate during flight.
11. Safety equipment: Safety equipment includes fire extinguishers, life jackets, emergency signaling devices, and other equipment that is required by regulations or is used for emergency situations.
12. Ground handling equipment: This includes equipment such as mooring lines, ground anchors, and winches that are used to secure the blimp when it is on the ground.

These are the main components of a blimp, but depending on the blimp's design, there may be additional or specialized components.

Please note that these are general components, the list might vary depending on the specific design of the blimp and the intended use.

What would be the size in cubic meters of the blimp envelope containing hot air suitable to lift the described blimp?

The size of the blimp envelope in cubic meters would depend on several factors, including the weight of the blimp, the temperature of the hot air, and the desired altitude of the blimp.

A general rule of thumb is that a hot air balloon's volume needs to be around 3-4 times larger than the volume of the displaced air at ground level in order to achieve neutral buoyancy at an altitude of around 1,000 feet.

The weight of the blimp you described that can hold 10 people and has 2000 square feet of space would vary, but as an approximation, it could be around 2-3 tons, including the envelope, gondola, and all equipment.

The temperature of the hot air would also be an important factor, and it would need to be quite high in order to provide enough lift to support the weight of the blimp. The temperature would need to be at least around 100-120 C.

With all these variables in mind, calculating the exact size of the envelope in cubic meters is a complex task and would require detailed information about the specific design of the blimp and its intended use.

Assume the total blimp weight is 3 tons. How many cubic feet of hot air would it take to lift the blimp to 7000 feet using an ideal envelope shape?

It is difficult to estimate the exact volume of hot air required to lift a 3-ton blimp to an altitude of 7,000 feet using an ideal envelope shape without knowing more information about the specific design of the blimp, the temperature of the hot air, and the properties of the materials used to construct the envelope.

However, in general terms, the volume of hot air required to lift a blimp is directly proportional to the weight of the blimp and the altitude it needs to reach. The higher the altitude, the more lift is required, therefore more volume of hot air is needed.

A rough approximation using the ideal gas law PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature, assuming a temperature of 120 C, and a pressure of around 0.1 atm at 7000 ft, would yield a volume of around 800,000 cubic feet.

Please note that this is a rough estimate and the actual volume of hot air required would depend on many factors such as the blimp's design, the properties of the materials used to construct the envelope, and the temperature of the hot air.
