Launch support: Managing complementor bottlenecks in the disruptive innovation of small satellites

Strategic Management Journal, Volume 47, Issue 3, Page 758-803, March 2026.
Abstract Research Summary Through both qualitative and quantitative analyses of large‐rocket providers' support for small‐satellite manufacturers before the emergence of small rockets, we examine how disruptors to an incumbent ecosystem gain support from complementors of the incumbent technology.

The Role of Creativity and Innovation Management Research in Times of Changing Security and Defence Realities

Creativity and Innovation Management, Volume 35, Issue 1, Page 84-90, March 2026.
ABSTRACT Geopolitical uncertainties and the resurgence of security and defence needs present both opportunities and challenges for creativity and innovation management. At both the organizational and the individual levels, we are confronted with multiple ethically challenging choices. Given the changing global security and defence realities, we outline

Study on Thermal Degradation Characteristics and Regression Rate Measurement of Paraffin-Based Fuel

Energies, 2015
Paraffin fuel has been found to have a regression rate that is higher than conventional HTPB (hydroxyl-terminated polybutadiene) fuel and, thus, presents itself as an ideal energy source for a hybrid rocket engine.
