The future will be an exciting place. The SM-150 will enhance the excitement. A Sport Aircraft for a new era, the SM-150 looks like an aircraft of tomorrow because it is. It’s a stylish, next generation sportplane that will be affordable to the general public. It is the type of aircraft that will inspire people from all walks of life to become pilots. It will appeal to tomorrow's generation while still exciting seasoned pilots of all ages. 

Anyone who loves science fiction developed certain expectations. The SM-150 is about fulfilling them. For some it will be the closest they will ever get to flying a spacecraft. To others, it will be the first step. It’s about living in a ...

CU Skunks at the University of Colorado Boulder has designed a Vertical Take-Off and Landing (VTOL) aircraft and aims to fabricate this aircraft with a special carbon nanofiber (CNF) reinforced composite to achieve near-zero radar cross-section.

VTOL capability combined with stealth technology gives aircraft the features of hovering and reduced radar cross-section, i.e. low observability. The transitional motors on the wing in vertical configuration accomplish the vertical take-off and landing and in horizontal configuration accomplishes the cruise phase.

Typically, 65% of stealth is achieved through the design of the aircraft and 35% by radar-absorbing material (RAM). Achieving stealth through aircraft design calls for major aerodynamic compromises in terms of stability and control. The F-117A Nighthawk, with its ...

Orbital insertions by vehicles require narrow calculations. To increase windows, envelopes, & possibilities matter displacement may work given enough power or tools. The analogy of a bubbled Olympic pool or a diving sub, ship, or diver might suffice. With a laser or subship or peeling device perhaps the atmosphere could be displaced or bubbled or caused to be less dense for a second, boiled or steamed even, making it less "rock" hardness. Slowing down or increasing density or shielding works, too. But, basically can a hole be put there and a vacuum or bubbling in air? With lasers or energy. Could be ground base or satelite assisted or a shell or chemical. A vortex by dispersant and beam? Peel, ...

Space travel is time-consuming and expensive. Thus, a “Common Habitat” that can be used by crew in microgravity (transit), one-sixth of Earth’s gravity (the lunar surface), and three-eighths of Earth’s gravity (the Martian Surface) with minimal adjustments to the internal configuration is ideal. The Common Habitat is a fully functional and outfitted habitat to be used in tandem with the Multi-Mission Space Exploration Vehicle (MMSEV) as well as the Jet Propulsion Laboratory’s (JPL) All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) rover and various other Martian lander concepts. I designed both vertical and horizontal configurations of the Common Habitat; future studies will evaluate both, and determine which configuration is better for the crew from a human factors perspective. Previous habitat studies have ...

NASA's Langley Research Center has developed an inexpensive, long endurance vertical takeoff and landing UAV. It is capable of flying for 24 hours, landing in a 50 x 50 zone, and can be loaded into the back of a cargo van for easy transport. In addition, it can land in an either horizontal or vertical flight configuration. The vehicle can be used in any application where UAVs are needed to take off from, or land in, an unprepared landing area.


Can take off and land vertically, as a helicopter would, without any support equipment such as a catapult launch or capture nets
High aspect ratio wings result in 24 hour endurance which is unmatched in the industry

An efficient, geared turbofan jet engine with reduced complexity and cost compared to conventional alternatives. I have talked with experienced technicians, as well as done some extensive research on the technologies involved, and have revised this concept over the past year and a half. As modeled, it is not 100% ready for commercial use, but it is easily modifiable by willing and able manufacturers in the aerospace industry to fit existing engines and components.

This designed system is a replacement for the dual exhaust stages of traditional axial flow jet engines with a single stage, high RPM optimized turbine called a Tesla Turbine. This 105 year old design never quite went mainstream due to its tendency to dangerously warp ...

At present and in the future, flying vehicles (as well as drones) will flourish. They needs compact and powerful engines, friendly to the environment. Four-stroke engines as well as turbine engines are not suitable. This engine will replace those engines.

The Wankel engine does not have a separate lubrication chamber. The lubricant is mixed with fuel and injected directly into the combustion chamber. As a result, poor lubrication, reduced quality of exhaust, less durable. Turbine engines are low efficiency when small in size, very high production techniques, high maintenance costs. Therefore, expensive price, not good for small application.

This engine solves the above problems. Each rotor when combined with the body will create three chambers. Two chambers are ...

Underground hydrocarbon spills (approximately 10m) are common, generated in hundreds each year worldwide. They are mainly due to the wear and tear of pipelines in the oil industry, insufficient maintenance of refineries or the wear and tear of storage tanks and pipes of those industries that use refined hydrocarbons to operate. From the Mars exploration application the proposal is innovative and tackles a very important, recent and interesting issue regarding human exploration of other planets and should be considered because is a simple way to solve a relevant matter for the goal of human exploration of rocky planets and the possible organic compounds on them.

The oil spills generate an environmental problem and an economic waste for ...

The VForce® invention is a major evolutionary step in fixed wing aircraft development. High lift devices (flaps/slats) have not significantly changed since the invention of the Fowler Flap by H D Fowler in 1924.

The invention provides a lighter, less complex high lift device deployment mechanism that does not require under wing fairings and reduces fuselage shock body size all combining to reduce parasitic drag. Cruise flight drag is reduced and therefore less fuel is carried and consumed allowing for a higher pay load or increased range while providing a reduction in greenhouse gas emissions.

The VForce® invention also allows for the morphing of Rotorcraft blades with greater efficiency. The sealed leading and trailing edge joints also provide greater efficiency.

Rotorcraft blades ...

The development and production costs for VTOL aircraft are very high. An obvious way to reduce these costs is to use components from the existent aircraft. Reusing a larger and highly complex component induces lower costs of development and production. In this presentation, it is proposed to re-use the entire fuselage from a commercial airplane for conversion to VTOL aircraft.

The new VTOL aircraft concept with Distributed Electric Propulsion

Within the present concept we wish to develop a "best in class," advanced VTOL aircraft system utilizing the new Distributed Electric Propulsion - DEP, combining the Vertical Take Off and Landing capabilities of a helicopter with the horizontal speed and payload of a traditional jet airplane. This new VTOL aircraft ...
