Mighty No. 9 is a side-scrolling action game takes the best elements from 8- and 16-bit classics that you know and love and transforms them with modern tech, fresh mechanics and fan input into something fresh and amazing!

In the year 20XX

Our hero Beck is the 9th in a line of powerful robots designed to compete in spectacular duels in the Battle Colosseum and is the only one not infected by a mysterious computer virus that has caused mechanized creatures the world over to go berserk.

Run, jump, blast, and transform your way through twelve stages using weapons and abilities stolen from your enemies to take down your fellow Mighty Number robots and confront the final evil that threatens the planet!

The Kickstarter sensation from an All-star Dev team!

Every aspect of Mighty No. 9’s development—art, level design, music, programming, etc.—is being handled by veteran Japanese game creators with extensive experience in the genre, all the way up to and including the project’s leader, Keiji Inafune himself!

Mighty No. 9 began life as a wildly successful Kickstarter project in 2013, where over 67,000 fans (plus later a further 5000+) backed the project, raising over $4 million in the process, making the game a reality. Without the belief and support of these backers Mighty No. 9 would not exist today.

The blade moves forward and backward in the plane of rotation to relieve Coriolis forces caused by flapping.

Academic validation for the book is overwhelming. It is a staple in university curricula, forming the basis for courses at institutions like The Ohio State University, Boston University, and Georgia Tech, where it is listed as the primary textbook for rotorcraft aerodynamics. One reviewer notes that “Professor Leishman has provided a significant addition to the literature that will prove its worth for many years to come”. Another states that if you can have only one book on rotorcraft, this should be it.

“The rotor does not forgive ignorance.”

Helicopter blades are not rigid; they flap, lead-lag, and feather. Leishman provides a detailed mathematical formulation of blade dynamics, explaining how centrifugal and aerodynamic forces influence blade motion. This is crucial for understanding rotor stability and control. 4. Aerodynamics of Forward Flight

Principles of Helicopter Aerodynamics by J. Gordon Leishman: A Definitive Guide

By applying the conservation of mass, momentum, and energy, Leishman demonstrates how a helicopter accelerates air downward to produce thrust (

The book has been published in several editions, each reflecting the evolution of the field. The was released in 2000 (ISBN‑13: 9780521523967) and established a new standard for helicopter aerodynamics texts. The seminal second edition was published in 2006 (ISBN‑13: 9780521858601), significantly expanding the scope of the original.

Digital versions allow engineers to quickly find specific formulas, definitions, or equations.

In high-speed forward flight, the retreating blade must operate at a very high angle of attack to make up for its low relative airspeed. If the pilot tries to fly too fast, the retreating blade exceeds its critical angle of attack and stalls. This causes a sudden loss of lift, severe vibration, and an uncommanded pitch-up and roll. Compressibility and Shockwaves

While it demands a significant commitment from its readers, the payoff is a profound understanding of one of the most challenging and fascinating fields of engineering. For anyone serious about rotorcraft—whether a student, researcher, or practicing engineer—Leishman’s work is not just a resource; it is a necessity.
